Those cheaper screw in tanks have regs and output at the same pressure as co2 tanks do, but do not freeze or spit out liquid. Those only cost $100 or so, not a bad option. The tipmann is not a bad gun, so upgrading to a super finicky non-electro would be pointless. If you want a new gun get an older impulse or DM4 or something, no need to blow over $1000 on a gun/tank/hopper quite yet, on top of tourney fees, traveling, practice (you will need to practice a lot outside of open play at your local field) etc.
