Nigel,
The Peavey Classic 30 with 1 12" speaker and Classic 50 with either 2 12" or 4 10" speakers are both great amps. The peavey amps are american made, the fenders are made in Mexico, and are priced less than the Fenders. All and all, both brands are very good quality although for most, the resale value of the Fender's are probably a little higher.
