If you know of any snooker tables in your area that aren't listed on findsnooker.com, please let me know.
Getting a custom snooker cue in the U.S. is tough. Last year I found a reference to a snooker distributor at some pro shop in a New York pool hall, but I can't find it any more. In Houston I think there may be a shop that imports snooker cues. Given the number of snooker tables in California, you might find some dealers there who sell snooker cues.

Peruse The Snooker Forum and read about snooker cue makers. You'll find reviews and debates about various snooker cue makers and their cues.

In the near future Mike Wooldridge will make his Virtual Cue Maker available. I played with the software when it was in beta and found it to be wicked cool: you can choose the wood and set other options and see a picture of the cue as you "build" it. (I have a Mike Wooldridge snooker cue.)

I would also recommend contacting user ADR147 here on AzB; he sells snooker cues from the UK. For advice consider contacting drsnooker, Wity, DKhan, and others who post in this forum regularly.
Good luck!
