The difference in value is purely in the publics perception of the .me.uk and .org.uk domains.
If looking purely in off-line marketing perpective, then no doubt about it, .co.uk is streets ahead.
However, on-line, as has been said many a time, in terms of Google, there is no difference between .co.uk, .org.uk and .me.uk. So in trying to get a site ranked on Google, they have the "same value".
I believe the value really depends on the genre of the keyword(s). If your site is offering a personal service, then the .me.uk variant has a certain ring to it and therefore the value can outweight the corresponding .org.uk.
I think it is wrong to generalise about 1/50th. There are some domains that you will
never be able to buy, as the domainer is in it for the longer time, or it's owned by a competitor, so what is the next best option?
Yes, I do have a vested interest in promoting .org.uk and .me.uk as I have picked up some decent keywords on them, but I wouldn't spend the money if I didn't believe what I was saying. I've turned reg fees into £xxx on some of these domains, so they can't be that bad!!
