I could probably afford the £20,000 or so they generally go for but the marginal improvement in sound quality over the instruments I already own isn’t worth it; plus would I really want to drag one along to a local session?!

To may people, price seems to be a major issue. The way I think of it is that if you’re prepared to spend several thousand pounds for a car which you leave to rot away on the drive or street outside, why are you not prepared to spend a similar amount on a guitar which, over the same period, costs less to run, will improve with age and probably be worth more than you originally paid for it. I certainly know what I’d choose.
