Well, where do I start. I can't believe how SWEET this marker is. I got a great deal on mine [Got it used], and it came with a CP reg and a Palmer Rock LPR, along with a NoX Board already in it. The thing was RIPPING! I had no problems with it at all, it shot soooo smooth, and it was shooting accurate although I have not mastered balancing the regs on it. For the price its going for right now [used], its VERY worth it. I love it to death, I liked it INSTANTLY over my Promaster [which is highly upped right now].
Find a cheap one, and get it, its the smoothest marker I have ever shot. It's EXTREMELY balanced, and feels GREAT in your hands, definitely worth your attention.
