Empire E-Flex, great lens view, great breathability (probably the best of all the masks on the market) and they fit glasses comfortably (at least on me anyways)
BT TM7, never seen a Q-Loader on one myself might be cool.
Empire 68/4500 tank, I think it's the best size and the Empire tanks seem to work great and are usually the lowest cost tanks on the market.
I mostly see Gen X Global tactical vests at my field, havent really heard any complaints about them even though they are one of the cheaper tac vests on the market.
Dye makes some nice ones too, thats probably the second most common one I see.
Hope that helped you out.
