Okay, thanks for the replies. Let's evaluate the key suggestions so far:
1. Feline Guitars LP - looks stunning. I forgot to mention that I have a £ 300 price limit in terms of the family whip-round.
2. Kelly Brook. Great idea, splendid balcony. Wonder what she'd give me for £ 300? There's a whole new thread there...
3. A nice watch. I recently did something really silly on ebay so I already have this and a scary creditcard bill.
4. A stairlift. Don't laugh sonny, you've got all this to look forward to.... that said, many a drunken evening this would have come in handy, especially if it had a commode under the folding seat.
5. A holiday / vouchers towards - actually a great idea, I've always fancied a trip to Memphis and then down to the delta so this could be a winning suggestion.
5. A new (landmark) guitar. Funnily enough, I've been thinking of putting a recent bit of good fortune money into an ES 355. This could give me the excuse. So, which BKP's would we put in a 355?
Now then, check this bad boy out:
