gb7519: You don't need to "break the bank" to get a decent regulator these days. In fact, you have to try really hard to find a
bad regulator. If you buy a regulator in the "middle" of the product line from most any of the major manufacturers you'll end up with a good regulator.
An important decision (
THE Decision ) is really where you plan to have your regulator serviced.... this influences whether you decide to by from the local LDS or online. If you like your LDS and feel that he/she will provide quality service (not all are created equal when it comes to servicing regs), then stick with your LDS. If not, shop around.
Mares makes fine regulators. So does Scubapro, Apex, Aqualung, Oceanic.... the list goes on. The nice thing is
you get to choose what you like the best, and as I mentioned above, it is pretty tough to make a bad choice. So if you have your heart set on Scubapro, go for it!
By the way, my regulator is a Mares MR-22 Abyss which I really love. I'm sure I would also love most regs made by Apex, Atomic, Scubapro, Aqualung, Oceanic, Zeagle, Dive Rite.... see a pattern?

Lot's of great choices out there.
Have fun!
