They occasionally come up for sale on azbilliards--and for much lower prices than new.
I bought one a few years ago in the For Sale forum. The shaft was warped, and the hit felt dead to me, so it just sits in a case. The Becue butts are super skinny as well, maybe the skinniest butts made.
You can get the leather wrap, but you can't get a radial joint on the butt. The only specs you can choose for the butt are the length and the overall cue weight.
An interesting tidbit about Becue...
Becue makes a mid cue extension as well as a rear extension. Presumably, the whole reason you would buy a Becue is to experience the hit of a 100% carbon cue. The rear extension is carbon, so when you attach the rear extension to the cue, you still have a 100% carbon cue, but the mid cue extension is made out of plastic. What the?? Doesn't that belie the whole sales pitch about how a full carbon cue hits better? Apparently, you can insert a 4" chunk of plastic in the middle of the cue and it won't affect the hit.
