Hi,
low to mid £xxx seems about the limit for the very BEST .org.uk's at the minute. Many are only worth regfee. There are lots of LLL left which limits value. My belief is the best ones will be worth a lot more in the future.]
What's good about this domain is it's 'CBT'.
That's ,amongst other things, compulsory basic training for motorbike tests. Everyone has to do this first (after the written i think) before going for the main test. It's well known as cbt. I would email a few firms running these tests & see if they want a cracking memorable 3 character domain. If you're only asking £200 - £300 , i think you have a great shout of shifting.
cheers, Guy
