Where to buy Extract Kits in UK?

Hi all,
Looks to me like partial extract brewing is a lot more popular in the US but the idea really appeals to me.

Midwest and Northern Brewer seem to offer a great range but with the exception of one very limited choice supplier, I've yet to locate them in the UK.

I know I could probably construct my own kit but the idea of having everything pre measured in one box does appeal to begin with.

Any advice appreciated

Cheers

Have you tried The Home Brew Shop? I've never ordered any kits, but they seem to have a few. You can order them online, delivery only takes a couple of days.
