The BIG problem is it takes him weeks or months to ship your order. SLOW, SLOW, SLOW. Do a search for KegKits on this site to see what people have said about Tom Hargrave, and KegKits.com before you order!
Hmm, Beverage Factory has aluminum and plastic :/ I swear I saw some 4 ways for $55 or so recently (I'm going to be looking into upgrading that crappy upright + cobra tap into a real keezer soon).
Looking at my LHBS site, they have a two keg manifold for $29 with additional lines going for $10.50, which sounds pretty awesome to me (NT = <3 but I know their website is, eh...), so I think that's what I'll be going with.
I LOVE kegconnection.com! I ordered my kegging gear from them, and I'm going to be ordering a manifold from them next. (I have to wait a bit- kinda on a budget at the moment, though).
