People on this forum along with tons of other forums will hate on anything aim has...
Nearly my whole setup is from aim, Yeah, I've had problems with it, but they've been pretty good to help me replace / fix anything thats broken.
With that being said, I am running the 1/2" plug and play, consisting of the new "air engine", and the dc7500 compressor. This was a HUGEEE upgrade to my old plug and play that consisted of the 1/2" "red" valves as they call them. that thing was nothing but problems...
I run the new plug and play on my daily driver, and have had zero problems out of it. Not saying its the best kit out there, but its pretty good in my honest opinion.
here are some pics of my plug and play.
