Anyone able to recommend companies that are trustworthy and reasonably priced for registering .orgs and .org.uk domains?

In the past I've used Easily.co.uk and I've had no complaints about the service but for mass registrations I'd prefer something a little more cost effective...

Anyone got experiences of working with 1&1 or xreg - I'd prefer to pay by creditcard rather than paypal etc.

Help anyone?

Reliability and good prices for all .uk domains you should take a look at 123-reg.co.uk
They can however be beaten on prices for the more "traditional" TLD's like .com, .net, .org

I register all of my domains with the above company as I like them all in the same place.
I would say get your .uk's from them and your .org's possibly from somewhere like Godaddy.com

GoDaddy does .uk. I've had no problems with them.

i use enom it seems their .uk system has improved (.co.uk) not sure about .org.uk though
