PSA: Peavey Max 110 really cheap at GC.
I just picked up a new 20w Peavey Max 110 "practice" amp on clearance for $49, about $100 off regular price at Guitar Center. They had 2 left. I haven't been thrilled with my Boss ME-20b with headphones so this will fit the bill nicely.
I spent more on picks and strings than the amp!
