I have only heard excellent feedback about the Roland Micro Cube. Apart from my dream amp I'd say I was quite impressed with the first series of the Valvetronix Heads. I once played that thingy for a while in a rented and equipped rehearsal location. I'd say that was quite a bang for the money. Still my Line6 Flextone I - yes, 1, first series ever - is an excellent amph.
The bang also depends on what you prefer, so I guess 1000 sounds can't satisfy me if THE sound I am looking for can not be produced.
Currently I am gassing for a Bogner Goldfinger 45, but hey tell that to my wife and I can pack my things an move out :-)
