What you pay in $ in the US we often pay in £ in the UK. It's a bad deal for us, and why my last 2 cameras and some accessories have been grey.
I buy a fair bit of used stuff, and do that from a dealer with a guarantee, I buy the odd new bit or bob here and there, mainly for video stuff, like cans, or sticks, and tend to use Calumet, or Jacobs before they sadly folded.
Jessops were crap, and would only use them if they had an exceptional promotion on, or needed a spare battery like NOW.
I plan to buy a C100 sometime this year, and will probably be going to Calumet.
For me, it's the service, the ability to hold something, I really want to support the high street and local shops, but I don't want to pay 30% more than I have to, especially on the expensive things like bodies.
Canon need to give the little guys a break, their minimum accounts are terryifying for small shops. If all thats left to buy your camera from on the high street is Tesco, then ultimately it will be the manufacturers who lose out.
Jessops made some seriously bad business decisions, and as a company, deserved to fail (no disrespect to store level staff) but even the good guys are struggling.
