...do you think the MC225 would be the best value ?Best value? Dunno. They go for about the same as the MC240. But the amp only has 2 gain stages (as opposed to 3 on the MC240) and the 7591A tubes make for a very sweet sound. I've owned lots of tube amps but this one is my all round favorite.
All the amps you listed and are being recommended are wonderful. I think the MC225 is special but you really need to hear a few so that you can judge for yourself. If you but a good amp at a fair price you will always be able to sell it for at (or near) what you paid.
