Tank, everyone has some great advice for your questions and I am by far a huge Scubatoys fan. Since you are in Houston try checking out
Gander Mountain on 45 North in Spring. It may be a bit of a hike but they have a pretty large SCUBA area with a good selection of items from multiple manufacturers with very good prices and a helpful, knowledgeable staff. I have been in that dive shop in Webster you mentioned and found them pushy as well. There are some other good shops in Houston but you'll probably have to drive a little for some better service.
Bubblehead's SCUBA - On the North Side, brand new shop, really nice guys running the place, thet do Genesis and Oceanic.
Gigglin Marlin - Never been to their shop but want to, I did meet a couple of their employees/divers diving at Aquarena and they were really nice.
Hydrosports - the dive shop in Lake Jackson for Mammoth Lake, Brand new store Pictures look great.
WW Diving - Another little hike to Humble, this shop comes highly recomended from a good friend of mine (yet another I would like to visit.)
Kickady SCUBA - is in the Woodlands and is run by a really nice family that just loves to dive, and they have a Tiki-Bar IN THE SHOP!!!
Houston SCUBA Academy - I'm pretty sure this is the oldest dive shop in Houston, I got certified through a sister store (now defunct) back in 1989, there still in buisness so they must be doing something right, good size store and they're a Scubapro dealer (best regulators in my opinion.)
Also check out the
City Of Houston Underwater Mariners Social Diving Club - or CHUM for short, a great group of fun loving divers in the Houston area who dive a lot and have monthly drink-er-I-mean meetings at the
Stag's Head Pub near downtown.
Don't forget
SEASPACE is coming at the end of March to the Reliant Center, Awesome SCUBA convention and great place for killer deals on gear and travel.
Hope this helps, PM me if I can give any other assistance.
