Whatever you decide, shipping may be an issue with cost and possible duties. I recommend ordering online from a local ie UK retailer or site rather than from your location. And don't forget amazon.co.uk - Amazon truly has an amazing range of oroducts/suppliers/retailers now and I often use their international sites. Shipping is very quick too.
If you have a few general ideas in mind perhaps a post on the UK forum would invite some suggestions re local retailers.
