Drop a line to "drsnooker" here on the AzBilliards forum. He's a helpful gent.
I'm just about done compiling my list of U.S. pools halls with snooker tables. It'll be online in the next few weeks. In the meantime here are unconfirmed listings for snooker tables in Texas; by "unconfirmed" I mean I haven't called them yet to check the size and number of tables.

Contact "drsnooker" about his private 6 x 12.
Again, one or more of these locations may have closed or sold their snooker table(s). Some references are from old web pages and blog posts. I suppose I could have waited to post the list, but if you're headed to Houston or parts north soon then you'll probably want the list now rather than later.
Finally, I strongly recommend spending quantity time at
http://www.thesnookerforum.com/. There are many, many posts about cues. For instance, you might want to see if you can pick up a used Trevor White cue (usernamed "Trevs1", or something like that); his name is mentioned on the forum frequently.
