Budget would probably be about $375.00 US, but that doesn't buy as much here as it would in the USA.

I really don't want to go over 30watts as I have my neglected Marshall.

I want the convenience of a 1 speaker combo with a little more grunt and a few effects.

Yet another sales guy is strongly recommending the Roland Cube 30. I will try it out Wednesday when I go to the 'big city' :D

Any problems with this one?

CYA.
