My acoustic live setup right now is an old Yamaha F-310 with a Fishman Neo-D single coil and it sounds amazing. The guitar was about £50, you can buy them brand new for about that price but I like my guitars played in, and the Fishman was £40 brand new from ebay. So a gigable acoustic for £100 all in. Bargain. So yeah I'd definitely recommend Yamaha acoustics also, I've never played one I haven't liked.
I also just picked up a 90's reissue Danelectro 56 (the U2 one) for £110.
It's a cracker.
