I have had nothing but great experiences with,
Different Kitchen Records,
Monkey Boy Records,
Drunken Sailor Records.
Fast delivery and super friendly service, they normally all throw in a sticker or two as well.
Brassneck records are fantastic too. The owner sold me one of his own preordered Larry Arms records a few months back at no extra cost, great guy.
Another shout out to TomorrowBelongsToUs, the guy was late in posting my order, but threw in a few 7"s when he did.
And finally Rubber Factory who after a delay in posting, upgraded my Sainte Catherines record to a limited pressing and threw in a shitload of 7"s and stickers.
I've been lucky to never have a bad experience with any distro or label; each of these guys are fantastic.
