i'd just mention that stu/wab has previously take a lot of flack over people (me in fact) recomending kerso, vis a vis complaints from his competitors.

so its probably worth noting that tho he is very good he isnt the only ebay trader to offer this kind of deal - others include digitalrev and urgalaxy and many more beside.

Also with regard to the "valid uk warranty" this isnt quite so - you get a uk sales receipt which so far canon have honoured as valid - however as it is a grey import from the states and sold to you at a low price the receipt could potentially not be honoured for uk warranty if canon tighten up their checking of serial numbers etc

therefore although i have had nothing but good service from kerso on lower cost items, as you are spending circa £5k I would suggest that it is worth paying the extra couple of hundred quid to buy from a legitimate UK retailer rather than any ebay trader
