DNS stuff... Help with DS record?

Hey, anyone here know a reasonably priced DNS registrar that I could move my domains to?

Fasthosts seem unable / unwilling to host a DS record.

I need to host two org.uk. and three co.uk. domains, which presently cost ~12 for 24 months or so.

Would prefer (and pay slightly(!) more for) an ethical company, but cheaper is better overall, Im not made of money :)

Answers on a postcard?

Plz boost!
