SA shops...
I do most everything myself, so shops are a social place and where I go to get stuff to support the local economy.
Depends on what you're looking for. If you want to support an Indy, hell of a nice guy, and true LBS community/cycling advocate Reed from the Hub in New Braunfels is the man.
If I don't feel comfortable doing a job myself or need it done and I don't know how, hands down Dr. Carlos... no store front he runs it out of his house and travels, but when I think I'm a bike geek I talk to him and realize what a rank amature I really am. He's a great guy and know more than anyone I've met in my cycling career.
Where I go if I need stuff right away BW in Alamo Heights. sslos works there and is one hell of a guy. Jeff works there also and is a fellow Mojo. They score the majority of the business I would otherwise spend at an online retailer. Typically if they're within 20% from one of the online whore houses I'll suck it up and buy there because I want LBS to survive and they're down the street from one of my offices so it's convenient.
If I need road geek stuff Britton's. I hear Jimmy isn't the nicest guy below the surface, but he's alway been friendly to me and I know he'll work a deal and doesn't take it as a personal attack.
The last place finisher, mainly because they're the furthest away from me would be Bicycle Heaven. On occassion when visiting my mom I'll pop in there. They have a so so selection of stuff, good road stuff (moots dealer) and one of the few shops I know that carries Cross stuff. Their prices for the most part blow and they cater to the wanna be elite Stoned Oak crowd. They also consider themselves a "boutique" shop <snicker> and have lame hours.
That's Fat Bob's world. I'm sure there are tons of others that are good, but that's where my dollars flow.
