Good luck if you get a DP. Personally it is not worth the experience to deal with him, or have his cue. I had one and it was a complete piece of junk. The joint was not even centered right. I got a DPR shaft as an upgrade and I also got a talisman extra hard tip that was slopped on, not shaped right, and dried glue stuck to the side of the shaft. You could feel the inlays and rings and there were indentions all around the cue.
What's more, is he is a total piece of crap. I would stay away from him, period. The attractive price is not worth the effort. Don't be fooled. There are many like the above posters who may be happy, and power to them, but you have a very good chance of being left with something very undesirable. If you really want to try one, deal with a trusted AZ member who already has one, and buy an older one. They are actually good cues. I had one. The new ones are cheap quickies that are pumped out of his shop just for quick turnaround.
The DPR shafts hit nothing like a predator, which is not just my opinion, that is a fact. It is a wannabe predator. Predator has a reengineered front end and special characteristics to it that DP couldn't replicate to save his life. OB shafts are also well made and are not the same as a DPR. His normal shafts are green as hell (not seasoned properly). The DPR and normal shafts hit like a marshmallow and have no responsiveness to them.
I would personally stick with Mezz. The way those cues are made are absolutely flawless and are probably the most well made, manufactured cue in the world. If you want a custom cue from a US maker, do your homework first, and get with someone who knows the ropes that you can trust. Take your time, and most importantly, avoid DP! It's a total waste of time, and a joke to even consider...... good luck
