There are none currently on eBay.co.uk, so I'm going to try there. I'll also try some of the reddit UK-specific groups.
As far as not being scammed - it's a really high value one-off sale, so it'll either be local pickup (and cash / bank-transfer at the time, which happens in seconds in the UK) or escrow.com (for non-eBay) with the buyer paying all the fees etc.
I'd prefer local pickup because then I have the money, the buyer can see it working, verify everything to their satisfaction etc. etc.

Thank you :) It is a little better today. Sitting down is now tolerable for short periods... :)
