I might be wrong on this, but if PRS can get punters to pay £300 quid for "Birds", fair play to them.
Oh yeah, I agree - I wouldn't pay for them, but people obviously will.
Like the £10,000 (or whatever) for a Private Stock guitar discussed earlier, there doesn't
need to be a justification for the price, it's a simple matter of "how much are people prepared to pay?".
It's a bit like the well-worn debate over whether Premier League footballers "earn" £50K a week. It's irrelevant whether they do or not, it's dictated by market forces - they're "worth" what their clubs are prepared to pay them.
