I won a Palmer on EBay for $42. Was it worth it, very much so. Absolutely nothing wrong with it. I shot a few games with it and it was ok, not outstanding or anything that would blow your hair back. The construction was well executed.
Keep in mind that there is no way that you will be able to compete with any of the Asian sellers on EBay. You probably will get the same wholesale prices as them but after dealing with shipping, taxes, duty, they will cost you considerably more. Pounding a few out locally would be your best bet.
I know, I tried it a couple of times.
I don't know if or how the Kao Fa wood company is affiliated with Kao Kao
or Tai Can etc, but they all do make nice cues and I believe that you will be amazed at the wholesale prices.
If you are interested in going that route, PM me and I will give you details
on a company in Taiwan that I dealt with. They are pretty obscure and you won't find them on any of the Asian Trade Market sites that Chris gave you. Can you imagine, paying $38 USD for a serious quality 3 piece J/B cue that can easily be sold locally for $100 plus? Of course take into account what I mentioned to you as over head. I don't mind giving out my lead as I mentioned, I tried it and the players in my city are cheap beyond reason and would rather play with a Wal Mart cue, the hassle and grief was not worth it any longer on my end.
