What the title says. I'm looking for small amps for my guitar (think play in my room); ideally as cheap as possible that don't sound like shit.

Things I've seen around are the Ibanez T10 (going for around $140), Freeman AK15 (I assume it's some kind of no-brand, these go for around $60) and Washburn Wa20 (which go for around $80)

Besides these, could you give me some advice on what to look for, or specific models that might fit what I want?
Is it really that hard to say whether any of those is a decent amp or not?

P.S. sorry about bumping so soon but the speed of these forums is retarded sometimes.
