Probably weren’t looking for a brand new line but I’ve heard some good things about them.
If you’re looking for new parts I use www.dynotunenitrous.com
These guys are great, ship quickly and back everything they sell. I think I’ve purchased at least one of everything on their site 
I usually look here first: http://nitrousoutlet.com/index.asp
