Looking for Sigma 70-200 f2.8 Nikon Fit

[Macc]

Hi guys,

I'm looking for a second hand (or cheap new) Sigma 70-200 f2.8 for Nikon. It doesn't have to be someone on here selling one but if anyone see's a good bargain on eBay or any other UK dealers then I would be much appreciated.
I'm looking at something between £300-400 and the seller has to be from the UK only.

Thanks in advance,
Chris.
