well I finally have the coin to buy a decent SLR. and was looking for some help with buying one. proably looking at spending $1500 for a decent twin lense kit. is it worth going second hand? I'm guessing I can buy alot more camera/lens second hand than new. any disadvantages to this? and what should I be looking for in a camera. I'm thinking the number of fps that it can shoot and sensor size are proably two of the most important things. if you've seen any good deals in the shops lately thaty would be good to know too.
