I think really the best option for you is buying a Kraken for $120 or whatever, putting in maybe $40-50 worth of upgrades into it and then gaming it for a year then selling it off. You might recover like $80 (half your initial cost) but it's still something at least.
Really that's the cheapest option that you have and they're not "bad guns" they just aren't that great quality (which is what the upgrades would be for, durability).
