I can personally recommend a few guitars. Firstly, A "Yairi" - they are one of the most underated guitars on the market. Mine plays like a dream and has mellowed well in the eight years i've had it. They now cost from £800 upwards. I bought mine for £200 (now that's inflation) they are all good quality hard wood. They have different models so try them all. Ivor Moraints stocks them as does Chandlers in Kew.
Secondly, buy a good Gibson - a well rounded model such as the SJ special. It is an all round guitar. I use mine for folk/blues/jazz and it holds it head up for all the above styles very well.
Yamaha do a hand built service - they come with electrics in (if not, wage a deal to get it put in.) They used to have examples in Chappels in Bond Street. The hand built guitars start from about £1,100ish.
good luck!
