A few thoughts on your querry
A custom sneaky pete runs about 250 from a decent cuemaker. Anything more is too much. I know bob frey makes them but they are not full splice cues and they are conversions. Dale perry makes them for under two hundred but his quality has gone down. Here is what I suggest. There are a few options for you.
If you have a predator now you can have a cuemaker match up your shaft to a sneaky butt. And you can use your current shaft.
Or you can have a sneaky pete made.
Micheal Wagner from raven cues makes a shaft several ways. He has a ton of different shafts he can make.
He can make a regular shaft, one that is built like a predator, or a regular shaft that is not a 8 piece splice but a regular one with the hollowed top area with stuff inside like a predator.
His sneaky petes are 250 but I am sure he can make one with a shaft of your choice for the same if not just a little more. If you go to ravencues.com and just play around you will see what I mean about his attention to building such a perfect playing cue. I own one now and I am also playing around with some of his shafts this weekend. I have one of his shafts on a 3000 dollar mottey as we speak.
The previous post was somewhat correct. You can buy a cue from a cuemaker for about 500 bucks with points, Jensen makes a great one for that as well as blud and Dale perry (if you tell him you don't want it rushed). Also CHeck out pat diveney from Iowa. He makes an amazing hitting cue for the money as well. The only thing I don't like about most smeaky petes is the wood to wood flat faced joint. I just don't care for it. Don't buy one to hustle with cause it makes no difference. Nobody bets according to a stick. If you want one for the simplicty of it.GREAT CHoice. But I would build one with a wrap and put the money into the shaft and joint.
Hope this helps,
