I imported a 41c about 2 years ago - it really is a fantastic amp. I play in a nine piece Soul / RnB outfit, and it has no problems at all keeping up with Horns, Drums, Guitar et al. Sound quality is spot on.
Tony Barbetta dealt with the mods required (transformer etc.) very professionally (he would not ship it until he had exhaustively tested the mods), so delivery was a little longer than I expected. However it was very definately worth the wait. Cost about £650.00 inc. import taxes.
