Scuba/Dive Gear

Where is the best place to buy dive gear ? Price and selection.
Also is there anyone here who does repairs?

Last year I purchased new dive gear before I went to Cozumel. After shopping several local stores in my town, I made my purchase on-line at divers-supply.com. The pricing was competitive and the service was great. Two weeks after I received my equipment, I tested it out at a local pool and decided that I didn't like the spare regulator I received. I called them up and the exchanged it for a better one in just a few days, no hassle. Plus they are authorized dealers for the brands they sell, that means full warranty.
