Hehe... One of the advantages of not having to queue with everyone else and getting there early (trade passes and pre-registration certainly saves a lot of hassle)!
Jacobs were given a load of kit from Canon to sell off on their behalf apparently which is why there was a lot of 'B' grade stuff there. There were four brand new 580EXII's for sale that had damaged boxes. They were all sealed with full manfacturer's warranties on them and they were selling them for £249. Within 20 minutes, all four were gone!
I wasn't actually going to get a 580EXII but for that price, it seemed daft not to!
Next year, I plan on going back there with a couple of grand if I can afford it.
