Which and where can I get a remote for my Nikon D3000?

I want a remote for my Nikon D3000 but I don't know which one to get. Should I buy the 20 pounds [expensive though!] remote from Nikon, or a more compatible remote that's like 5 pounds [found on amazon]
Which one would be better [I just want a simple remote - nothing fancy] and where can I get one? I'd prefer not to buy online -[i live in the uk] could I get them in an curry store or something?

Do they have best buy in uk? If so you can get one there. But other than that I got mine from amazon.com (amazon.co.uk for you).it's called the ml-l3 infrared wireless remote.

That is the one I have, and I own the D3000. Works like a charm!
