Funnily enough, for reasons of moving house, I now have to sell most of my guns and equipment, and I recently bought a Hawke Sidewinder HK4008 with SR6 reticule for just over £300 and a £20 set of mounts. Mint condition, used about 3 times - make me a reasonable offer! If you are interested I can get you some photos - but I chose it for many reasons (took about 3 months to decide) - full info here.
I'm not biased or anything but its an amazing scope, and with the software you can download from the site here, putting in all your ammunition and rangefinding details, you can get a printout of your reticule with all the different ranges for the various crosshairs!! That really satisfied my inner nerd .... also using the sidewheel you can get a fairly accurate range without too much trouble as well.
Let me know anyway - on here or PM me.
