Well,
This is only my two pence, but...
From what I can tell, this is JT's attempt at a "tourney-grade" marker. I'm so pissed off at that phrase at this point, though, as it seems that ****ing manufacturers have forgotten what that means. People release spyder clones left and right and then say things like..."At last...a tourney grade marker, made entirely out of plastic, assembled in taiwan that EVERYONE CAN AFFORD!!!!112!2"124444444" They seem to think that labelling a marker tourney grade makes it tourney grade. From what I've seen, these markers haven't cought on. Not even a little. JT has decided to go into unfamiliar waters and is trying to make paintguns...I think they would have been better off sticking to gear and goggles. But whatever. All I'm saying is, this marker has been out at least a year. I haven't seen a single one at the field I work at. I haven't seen a single one on the tourney scene. I haven't heard anything good about them yet on these boards (though I haven't looked for it specifically). I think if it was a better gun, then people would be using it, and, more importantly, defending it, don't you?
I say, steer clear of these and make up your mind as to what you're looking for in a gun. If you want a cheap-ish open bolt blow-back, then go off, get a spyder/tippman/whatever, and be happy with it. If you want a TRUE tourney marker, then suck it up, save your cash, and be prepared to dish out quite a bit for a proper electro. If you want a happy medium, get an autococker, mag, or electro secondhand...Prices go way, way down, and you can find some excellent buys.
