Great Outdoors Aquasports(512-453-1852)
Aquatic Adventures(512-219-1220)
Ocean's Window(512-258-8000)

Note that some of the price difference is wound up in 8.25% sales tax vs. 20 - 50 shipping.  The difference comes to about %50.  I gave the phone numbers not to be anal, but simply for those who wish to do their own research.  Of course this doesn't even get into the issue of availability, these are just the prices I got quoted.  Of course, in the defense of the dive shops, I probably could have gotten them to cut me a deal, probably about %15.  So the total markup could be closer to %35.
