My advice is, if you get used gear somewhere make sure a LDS services that brand. As long as you get good name brand gear, it should be fine. The top companies rarely put out junk. You also have to know what type of diving you are doing: A couple times a year in the tropics, or cold weather, harsh climate. Ask around, here in NJ there is a scuba flea market once a year, where you can get equipment dirt cheap. My buddy just got a used reg setup that would go for $500 in a shop for $50! Quality Zeagle reg/pony setup. There are alternatives to just paying through the nose at the LDS. Sometimes though, they do come very close to internet pricing!
