I've got the MiniMax that I bought NIB a few months ago for $259... I've only put maybe 500 rounds through it because the shells come directly back and bean me on the forehead every other time (gotta get the ejector adjusted).
No failures of any kind so far, and accuracy for such a cheap pistol is surprising. It even handled 200gr Hornady +P XTPs like a champ.
Though mine is a gem, I understand there are more lemons with Llama than most other manufacturers.
Good luck.
