Just to complicate matters: think about whether you would want a cut-away for better access to the upper frets. I would suggest that if you have aspirations to play anything rock-ish it would be useful to have one (in practical terms, this probably means you’ll end up with an electro-acoustic).
For me, it was a bigh step forward in comfort to get rid of my dreadnought and get a folk sized guitar instead. I found it much more pleasant to play, and easier to cart around.
I found that there was a huge choice of good guitars in the £150 – £200 price range. I got a Freshman Renegade, but was very impressed by the LAG Tramontane T66A. Also good were the Tanglewood Discovery, a “Richwood” brand guitar and Sigma (if you have big hands) or Seagull (for a bit higher price). The Yamaha APX400 felt good, but sounded a bit dead. Yamaha’s do seem to have very consistent quality control and play well, though.
Pick one you like the look of – it will encourage you to practice 🙂
Oh, and a big +1 for Justin Sandercoe’s Beginner’s Course – it’s completely free, but nevertheless truly excellent.
