ok, I found a marshall mg100dfx (combo, not head) for $220 on that www.craiglist.com should I get it? musicians friend describes the amp as being "a fully gig-capable amp". the amp costs about $465 new. it is a few months old and in like new condition. it's a solid state with 100W and a 12" speaker. it seems like an extremely good deal, should I go for it?
