http://www.dubmeister.co.uk/ is your best bet mate, there not going to be dirt cheap, i got offered some th monos for 800 with tyres, spacers and wheel bolts
just ask the bloke over email and ask if he has any special offers etc, as some people order wheels and dont want them in the end or they have small defects (which are only noticable up very close) so he does them a bit cheaper
