IMHO
Mares has about the best bang for the buck. (someone probably thinks Mares are junk)
As for service, it’s a crap shoot. Many authorized service centers do poor work.
Just because a shop is local doesn’t mean you will get your gear serviced to your
satisfaction.
Your regulators, in my opinion are the single most important scuba purchase
you will ever make. They will probably last you a lifetime and will effect you diving pleasure
and comfort. Not every one can afford $1500.00 for a regulator but don’t go cheap.
Finally if there is a shop with a pool anywhere near you, they may let you test out what
they sell?
