Also, if it is a MK-10+ (not just a MK-10), they are known to be "mushy", like the MK-20 (they use the same seat).

To eliminate the whistle the o-ring in the Mk10 body needs to be replaced with one in the Mk10 O2 kit. I don't have one in my presence to supply the part number. This issue is covered in Scubapro's reg clinic. A few years ago I had one that whistled and took it with me to the clinic to discuss the issue. The o-ring was replaced with the green one and the harmonic whistle went away. Easy fix.
The leaking is probably an adjustment issue. You should be able to take it back and have it corrected. It is the technicians responsibility to have it tuned correctly. Nevertheless, if you do not want to go back then you can take it to another person and pay to have it fixed.
Scubapro isn't the only one who operates this way. Other manufactures do the same.
I also hear the same complain with skiers. I work in an area that sells boats, RVs, watercraft, water skiing gear, and downhill skiing equipment. I hear the same comments, about older equipment / gear, as I do about scuba gear. The manufactures simply stop making the parts for the older gear. A third party may make parts, but it isn't always worth the store to buy from them, unless it servicing a lot of older stuff. In short, the scuba industry is not all that different than other recreational activities.

Thank you everyone for all of the comments. The MK 10 is the original model that I bought in the early 80's. I also have an Air 1 that I still have but swapped it out on muy reg for the G250 after reading on this board how well they work together. Guy at LDS sells other brands but Scubapro, but used to work at a SP shop. Thought he could handle this-but was wrong and I am disappointed. Does not make me want to spend any more money in his shop. Anyway, read on this board that all of my equipment can be upgraded internally to newer parts. I had some of the best times of my life diving with this gear. Would like to keep using if I can. I am not cheap-just appreciate good quality stuff. Would like to learn to work on my own regs, but apprehensive about fine-tuning adjustments and tools are costly. Would feel more comfortable letting someone "upgrade" the equipment. Realize a SP authorized dealer may not do this...

Also, where do you get the gauge to measure the creep? LDS showed it to me and said time to get new gear. I knew that wasn't the truth after reading tis board.

From reading the Board, these regs were so well designed that the guts can be interchanged with newer model parts. That is what I am looking to do, so they won't become obsolete.

Frustrating that someone took my regs, said they serviced them, charged me for it and then told me that I should just buy new equipment and kind of made me feel bad about the whole situation, like they were doing me a favor. I know from reading this Board that lots of people dive with vintage regs and are proud of it. I think it is pretty cool.
Attaching the intermediate pressure (IP) gauge to the inflator hose will allow you to view the MK10 "creep" described by your LDS, we can verify then if it is acceptable. No regulator work or disassembly required, but a valuable tool to have regardless of ones inclination to DIY on regulator repair.
If the guage shows the MK10 IP is acceptable, then adjusting the 108 to stop the free flow bubbles is easy to DIY. I started out using a flat head screwdriver from my tool box, but an official tool for the job is cheap enough. A few more small steps and low priced tools and the entire MK10/G250/108 setup can be adjusted or rebuilt. Any upgrades needed should have already been completed by the LDS during service, a few parts replaced on the G250 if it had older style poppet. Not difficult to verify if you have new style parts, post in the DIY section.
Frustration with LDS regulator service (on a new regulator I purchased from them) and making me feel bad is why I made the decision to learn DIY. I owe them thanks... Knowing how my regulators work and how to tune and repair them is worth the effort and cost many times over. I started out with the basic tools I needed for less than the cost of one LDS service.
It seems a shame to spend the $ to have the regulator re-serviced, but if you want to send it off, I have been happy with work done by Airtech on a MK10/109 in the past. I also expect you would be happy with work done by rsingler.
