I normally use www.ebuyer.com, and never had a problem with their service.

ive used these a few times also with no major problems, i had an order denied once, they sent me an email though, i just had to reorder and change one of the items because it wasnt any longer in stock, one thing though is their delivery isnt as good as it used to be, seems a little expensive and slow

Ebuyers are fine till you have to return somthing. then they leave a little to be disired.

Microdirect are good to deal with too.
