University Bikes is a licensed Litespeed dealer. They normally only have about 1 or 2 Litespeeds on the showroom floor though, so you would probably be looking at a special order purchase. It's a great shop, and they are really nice guys there. A little expensive. The owners also work at the shop. You should talk to either Manny or Carlos and they will take good care of you. Andres is the guy for fittings. Let me know if you have any other specific questions about them.
I've been very impressed with San Antonio Cyclery (which is the closest reputable bike shop to where I live). I'm a newbie and they've been very helpful and extremely friendly (to me and my kids) when I've gone in. I'm looking to getting a Tri bike next year and this will most likely be where I purchase.
FBS has changed since you've been there last. Brian no longer works there, and Hank from Chainwheel drive that we all love so much now works there. They have also moved (can't remember if you went to the new or old place).
Chainwheel was great though, bought my 'roo from there and got fitted by Hank.
UBC is okay but for some reason I wasn't too impressed. Haven't been to the others you mentioned.
I bought my Orbea from Mike (the owner) of Flatland Bikes in Tampa. He spent alot of time fitting me to my new bike and has been very helpful with adjustments, and speedy on the spot maintenance. He has some gorgeous bikes in there in a full range of prices and styles.
I buy many of my accessories and clothes from Chainwheel, since that is near my home. I biked shopped there as well and had an excellent experience, though I just couldn't find the perfect bike for me there, someone else may find their match there, very wide selection of bikes at both stores, Clearwater and Palm Harbor.
Not sure what you hate about FBS, but I had a good experience with them. They've done a great job of getting me what I wanted and I never had a problem getting in for the free maintenance or adjustments.
