domain stockforum.co.uk - greatfares.co.uk - need help

[xyberdomain]

I have a few .co.uk and a .org.uk domains that I have had for a while that are coming up for expiration. I have not see or heard too much about the market for sales of these on the boards or at dnjournal except for the occasional. Any board members knowledgable in these give me some feedback on the following:

stockforum.co.uk
greatfares.co.uk
discountapparel.co.uk (good overture)
prescriptions.org.uk

thanks.
