Yeah i had a play with a 1D and was amazed - unfortunately you cant use the lcd as a viewfinder but i doubt i would ever take it into a club so im not too fussed.
The new 1D van take 40 shots @ 8.5shots per second
the 300D can take 4@2.5 whicch is a huge improvment to my current camera which seems to take 1@1/4 sometimes.
I can see myself spending a packet on the accessories tho - so ill let everyone will know what i want for xmas and birthdays
