i agree the nylon collapsible crate is so handy! much easier to move around and take places than the wire one. We do have a wire one as well though, and only use the other one for night time and visits to friends houses.
We have a place called "ryans pet supplies" out here in az and that is where i bought my wire crate, $30 cheaper than at petco! It is 36x24 ish. the box had a picture of a chow on it, that's all i remember. If you have a pet supply store out where you live i would check there, but otherwise the best price you'll get on a crate is at wal mart. The nylon one is from overstock.com by a company called "go petclub".
I like to put towels or blankets in the crate when they are little, cause they are bound to pee on them and they are easy to wash. when he gets bigger you can get a crate pad that doesn't move around and is real cushy. piddle pads are a great product too. Get lots of treats, not crappy ones with weirdo fake ingredients though. Zukes, Natural Balance make good ones you can just quickly pick up from the local petco. The fewer ingredients the better. Toys! cause he's gonna want to play when he's not sleeping. Baby wipes for his lil' face, booty, and toes. FOOD. good food.
There's like a million more things i can think of :/ but i'll leave it at that for now.
