There have been many threads addressing this issue. Hopefully, someone will link to them and provide you with lots of reading, Mike. As to your question, the difference is £1400. For that amount, I could buy two or three excellent guitars.

If you are serious, go to large guitar stores and TRY the instruments. When you find one that does it for you, then ask about price, etc. I've come across some guitars that are excellent, and they weren't big names. A good guitar is a good guitar regardless who made it.
