TweetUG labs havent been around to long. Some of the most succesful have been
GAC or RSOC whatever the hell they are now
Spectro before they went defunct
IP(maybe not in quality but hes sold plenty)
PVL has me intruiged, as does the new Syrus labs, a well known LFC rep has stated some kick ass prices for this new lab in the future. And cheap 10mg var!
