1)  Ok, offering this here before putting it elsewhere so speak up if interested! 
 
This is a great value for money lens that I am reluctant to sell but I'd rather convert the value into something like a Canon G11 compact.  This is a constant f2.8 aperture lens that has been very lucky for me having won competitions or been placed several times with images using this.  However, last summer I upgraded to the Nikon 28-70 f2.8 to go with my D700 at 3 times the price of this.
It works great on a DX camera, very sharp after about f4, and I used it regularly on my D300.  On the D700 it performs very well and is a popular lens but, as you would expect,  there is nothing to match the Nikon 24-70 or 28-70.  For those you will pay £650 - £1000 secondhand.
Lens is in very good condition/excellent -.  Optically excellent and has the Sigma rubberised finish.  There is just a little dulling and buffering of this finish but it is very minor, looks good and comes with it's Sigma EX case and box.
If you are interested, it's £260 inc. special delivery.
I'm going to advertise it elsewhere in a day or so.  Alternative is collect from Leicestershire.
2)  Flash triggers: Also have a set of remote flash triggers made by ishoot/SLRkit.  This is a hotshoe mounted trigger unit and 3 flash shoes.  These are really for Canon with the dedicated shoes, but will trigger Nikon/generic flashes.  You can have the whole lot sent at £22 recorded delivery.
Not messing around, these are the prices and competitive to anywhere else, better than Ebay, so let me know if you are interested.
