£700 is not what it was! And you get a lot more bangs for your buck secondhand. If you want new in that range it'll have to be built in Korea or Indonesia or China. Some friends rave about the Blueridges but I think their sound is pedestrian in its roundness. I have a fiend who had a Breedlove that was nice, but I played a couple in shops and was not overwhelmed. I'd suggest trying a Faith - but not the mahogany ones.

Might be worth trying a Martin DRS2 - should be available at under £800.

I notice that Daions and Mugens seem to be going up on price (second hand) Might well be worth a look, but you will probably have to get your guitar fettler to install electrics.
