I've used a Fender Mustang II V2 for a year and a half now, and it's an amazing amp compared to the price. Great tone, insanely versatile and you can use the thing as an Audio Interface for recording stuff, and even comes with some recording software for making your own Backing tracks or full recordings! Quite possibly one of the best deals out there.
Other great amps I can recommend are the Peavey Vypyr and Roland Cube series amplifiers. Both of those also sound great, but I liked the Mustang's interface better.
