Fucking EPIC, brother...
That's exactly how I feel about PSA PA-10s... You can MAKE them work, with WORK. It's the lowest level of "probably operational for most people with most Wal-Mart ammo most of the time"... but it's far from a functional gun, as you receive it. That's why they're as cheap as they are. The only thing you could do worse is buy something from Davidson Defense, or any other name that that POS company operates under.
The PSA PA-10 won't categorically destroy your life, like CMMG parts will do, but it'll leave you pissed off until you get it right, and make it run - by making your own modifications to it that WILL make it run right. PSA certainly won't do it for you, with that "Lifetime Guarantee."
P.S. An adjustable gas block is NOT your answer to a PSA PA-10, to calm it's "over-gassing." It's not even possibly over-gassed, when it ships with a gas port diameter in it's barrels that is UNDER-SIZED... That's Unpossible...
That's a hint...
