I also think that the "B" just means it's a euro' model, I'm looking for the same camera, but I can't find it for that price!
The cheapest I could find was E-Buyer, but I thought I should try them out by ordering something cheap first, and they cancelled my order of some cheap DVD-r's and sent me an e-mail without much of an explanation.
So I'm currently looking for another place to buy one in the UK, Where were you going to get yours from?
Thanks if you can help.
Just had a look at e-buyer again, I think the price has dropped, but there aren't any in stock at the mo. Here's a link
