I ordered up from Keg Connection back in March - since the keezer project is still ongoing (and a pain in my arse), I haven't tested any of the gear yet, but my God, Todd and the guys were fantastic to work with. Customized my order to exactly match what I needed, and I got an upgrade to a 10lb tank at no cost (they were running a promotion back in February, and since my initial quote was given then, he still included it, even though I had to hold off for two weeks waiting for my @#$# tax return.)
Everything arrived really quickly, very well packaged, and I gotta say... pricing everything out, I got a fantastic deal. Went back to them for my Perlicks, and can't recommend them enough.
