Small and tough. Cheap at about $130 on-line. Good flow rate. Came with a Crossfire sticker and Paintball2Extreams magazine. I'm sure the tank is tough enough to bounce it off trees, rocks and heads and not hurt the tank.
Green, it could clash with your color scheme. The size, 68/3000, could leave you and your tank empty unless your field has HPA fills or you own your own Scuba tank.
Overall, a good first step into the world of HPA systems.
Mine came with a flaw in the plastic on the guage. Nothing too big, just big enough to be noticed and make you think it has a crack. It does not affect reading the guage at all. Mine also came with a leaky fill nipple. Crossfire does have a 1-yr parts/labor warrentee, but I just fixed mine on my own. To fix it I just unscrewed the fill nipple. It only had a small amount of loctight on it to begin with so it came off easy. I put on some teflon tape and wrenched the fill nipple on as hand tight as possible. Not a speck of air has leaked over the week since I fixed it.
Overall, a good little tank. Just be careful of how much you shoot in a day. If you shoot 500/day, a full tank should last all day on most guns. If you shoot 1000/day, you'll probally need a refill.
