TK sells at $55 the last time I was there.
to TS, your equipment will fit into the bag, and you should have some extra room for other things that you want to bring along.
if the dslr doesn't have a battery grip attached, then it's not too much of a worry. but if it does, then you will need to work out how you want to fit your gear in the bag. it's not impossible, but it's pretty tricky and likely you'll need to remove the lens from the body.
