Just one place needed - Electromusic in Copley Road, Doncaster. Everything from £70 beginners to £many thousands. Sit and play as long as you like, acoustic or through an acoustic amp. Best of all, ask for Pod. He IS the best salesman of musical instruments ever, absolutely no pressure, immensely knowledgeable about guitars (an excellent guitarist) and, for all the money I've spent in there he has even suggested a cheaper, better guitar than the one I was considering.
Good hunting
