theres a few
others, like Isaac pointed out, but this is In My Opinion.. one of the best for the 7th gen.. which is why i've stayed..
and it's very user friendly not too complicated ...
nor am i being bombarded with ad's..
people here are interesting bunch ..
a very diverse group in all ways
from knowing only how to put in air pressure to putting in a CAI
..etc..i've learned soo much from hanging out here
