Hehe, good to see a little giant fellow user. I just got my Little Giant 2-MD-SC fixed (bought it from ebay for $20, took the whole thing apart to get the danm bearings loose from rust) Chugs water like MAD. I'm sure the 3-MD-SC is even better
Yeah they do run hot and noise it hmm.. I don't know. just more noise (it sounds cool though, kinda like "HAAAAaaaaa" to me)
