i have found a guy who has amazing priced canon and nikon lenses
 

important: if someone is interested in this please be aware that i can take no responsibility for your transaction.I have found a man in scotland who has amazing value canon and nikon lenses, i have bought three items off him, a macro lens, a 400 f5.6 lens and a macro ring lite all at amazing prices, which is slightly more reduced if you pay him without paypal. On ebay he goes by the name of Kerso, but i will give you his email here so you can contact him directly with enquiries ;- kerso1123 'at' msn.com
he has asked me to recommend him and i am glad to do so.
if you live in the UK then i would recommend this chap, but like i said its up to you and its at your own risk. i saved 400 quid on my 400mm lens compared to jessops price. i am not trying to promote a buisness,i just know that this might be the difference from getting the ultimate lens. Like i said i do not know the guy well and cannot help you if things go wrong, all i know is i have saved money and would deal with him again and again.

I think you will find a lot of us on this site as well as members on Bird Forum and POTN have been using Kerso for a while. Ian (Kerr) is a top guy - I have bought three L's off him in the past year. The last one I bought off him, the17-40 f4 I also claimed the rebate back from Canon.

apart from his e-mail does he have an e-bay shop or something where we can view his stock and prices?

Just do a google for Kerso ebay. I Think his shop is named Flash Camera's.
He get the gear from the States and dispatches from Scotland so the end buyer has no duties to pay.

Do you get any kind of warranty cover? If so, who is providing it?

You get a Canon International Warranty.

Yes,this guy is a very reliable dealer.Also yes,you do receive a receipt which acts as a warranty.It does take a couple of weeks,sometimes,but he is 100% okay.
