I have a Lab Series L5 its the 100 watt version... great amp just need to change the speakers... havent done it with mine yet though. It was made by Norlin, the parent company of Gibson and Moog and contains parts from both companies. Mines die hard... hasnt died out on me yet... great amp.

ive seen some of these around ranging from $189 to $500... never a L3 though mostly L5s and L11s

Lab series are great amps, my bandmate has an L11 and it's one of my favorite solid state amps. He is trying to buy an L5 from a guy who garbage picked it. Who would throw something like that away?
