Freaks are decent barrels if you dont like the 2 piece design there is always the deadlywind carbon fiber that takes freak inserts.
the new empire kit that comes with the ressurection/sniper is also a decent kit
so are shaft kits.
if your just looking cheap sometimes i would suggest saving money, a good paint to bore match is always better for performance, so getting inserts or multiple sized backs is going to benefit you more than a one size fits all barrel
