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.
Weaknesses:
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.
Conclusion:
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.
