I've got the 3M PPS 2.0 adaptor. I wish the liners were cheaper and all you can buy is packs of 100 or a starter kit with 6 liners for $65 up here. I end up reusing the liners lol. From what I have seen unless you're spraying a whole car in an expensive downdraft booth you are going to get some crap in the paint so I don't see how spraying at home is going to be any worse if you build a decent booth. Also, you can rent booths in some places for less than it cost to build one.
