Disclaimer: I'm a complete newb, OW certified with 5 dives logged.
Off the top of my head, the LDS I certified with basically carried Oceanic gear, and a few other "lower" brands (ScubaMax included). I think it's fine, as students looking to get their personal gear for OWS certification generally don't want to pay top dollar for their starter gear until they know they want to commit the big $$$ to diving.
I bought my personal gear from the shop without doing much research, taking the advice of the shop owner and my instructor. I ended up with a ScubaMax Spider Eye mask, ScubaMax dry snorkel, Oceanic Viper fins, and Deep See boots. After shelling out the money and checking out the gear online after the sale, I discovered that I'd gotten a 2009 ScubaLab Best Buy mask, 2007 ScubaLab Best Buy fins and highly rated Aqualung-family boots. The snorkel, well, is a snorkel. After completing my pool work and cert dives, I'm still very happy with all of it.
So, don't completely judge a shop on the gear they stock, and don't judge all gear by its brand name. I actually liked my mask enough that after losing it after completing my cert dives, I went out and bought the exact same mask.
