Bluebonnet for me. They have great support and have on occasion been able to get things done when I was there if I arrived on my commuter rig with a busted spoke/bent derallier even when they had some other stuff in the shop.

RBM is nice if you know what you are looking for already in either a bike or bike accessories and happen to be close or in the area. They are far enough away from me that unless I have to go to the area anyways or to pickup another bike my wife ordered I'll just order something online.

I ordered my current ride from plano because they were the only ones around that sold it. I think they just took it out of the box and put the wheels on before giving it to me because of all the issues I had at first with it. They did take care of me when I quickly broke something due to their assembly issues. From what I understand they are the place to go if you are looking at recumbents, RBM has cattrikes but don't expect them to know anything about them.
