Where can I find a great selection of *quality* eyeglass frames?

I wear my eyeglass frames for years, so invest in high-quality, rather than budget frames. I stepped on my frames a couple of weeks ago and was able to bend them back into a workable shape, but there's a weakness in the metal that could easily snap. So, I need to replace them. Because my optometrist isn't stocking a lot of inventory right now, I need to find a place that sells a wide variety of top-quality frames and keeps a healthy inventory. I'm willing to drive w/in a 50-mile radius of Houston. Any recommendations? (FWIW, I'm looking for lightweight, low-profile metal frames (e.g., Lindberg, etc.))
