I've got a peavey rage 158 as my practice amp. Sounds good enough, mainly have it for its headphone jack. Unfortunately my Peavey Triumph 120 Stack doesn't have a headphone jack, and pisses my flatmates off to much.
Also, It's all about the pedals, I rekon get a good multi function one. My boss has one and it's amazing. It's a pain in my arse chaining all of mine together.
Some good reviews for the 158 here
