Instead of $130 to rebuild my ratty old Scubapro, I just paid $100 for a near new one on ebay !.....

I bought a MK10 g250 for $100 from a divemaster i knew in Cozumel, years ago, and as best i can recall, I never once used it. I just put it away as a spare, and then brought it back stateside with me about 10+ years ago.
Flash forward to now, and I'm gradually assembling some dive gear again, centered around this old MK10.
Well, I dug the thing out this morning, and it is pretty nasty (not unrepairable junk, but definitely needs the full treatment, new HP hose, at least, etc.)
I have a Scubrapro dealer/tech here in town, and he quoted me about $130 to bring it up to speed (about the same as a reputable place down in Florida did).
Meanwhile, last night I'd spotted a brand new ad on ebay, for a very clean MK10 d350, with full guages and BC hose, plus a bevy of other stuff, for $130 + $68 shipping.
The guy was over in Alabama about 90 minutes from me, so I messaged him an offer of $100 FTF, for just the MK10reg, the big zippered dive bag, and the large Cressi open heel fins......and he went for it !!
I just got back from the meet (super-cool guy that even met me halfway!!), and the regulator looks brand new ! It's got Oceanic depth and pressure guages.
I know I still have to run this old MK10 through the whirler someday, but for the moment, I saved money by just buying a new reg, and got some solid fins and nice dive bag, on top!
Won some, lose some !

So what are you going to do with the Mk10 G250?

if you are willing to go the DIY route, you can overhaul the mk10/g250 for about 40 dollars with service kits from vintage double hose

D series is not as good as G series …

Do you know when last your nearly new MK10 was serviced ?

A well tuned D series (and air1) breathes great. I still prefer G due to the adjustment knob and easily removable faceplate.

Yeah, I kinda suspected the G was better than the D, but I figured the price on the near-new reg was unbeatable, epsecially with the extras tossed in.
And, not sure when the 'new' MK10 was serviced, but it looks to be in pristine,low-miles condition (but, point taken).
And, I have been thinking about the DYI route, but I haven't looked into the details yet. Are there any good tutorials/videos for this?

Mk10/G250s are about the only regs I dive. However, I'd still recommend you get the "new" one serviced before using it.
