As for the camera, and this is just me, BUT I NEVER BUY NEW! Eventually you will want to upgrade and if you spend $1000 on a new body, a year from now it will be worth $600, as Canon puts out new Rebels every year.
Buying new vs used does have issues around warranty repairs and such. Like is the unit still in warranty?
Also, if you buy used, that is going to go down in value as well. Also, at this point, upgrading the camera every year is not something most people except some professionals do.
A good D-SLR can take decent pictures for several years. The megapixel race has gotten somewhat out of hand in my opinion. Also, do I really need my SLR to take movies as well? Movie cameras tend to have a form factor that is better for taking movies.
I have what is at this point a D-SLR that is over 5 years old that I got brand new. It still works rather well. I'd rather spend the money for lenses that I want at this point. When the camera needs replacement, I'll look at what is available and will still likely buy a new camera since they seem to last for several years. I haven't seen a new camera that adds any features that
I would find useful.
The various brands put out new cameras all the time to keep sales going. Mostly by people who must have the latest thing. (Even if the change is so minor you'll never notice it.)
Also, buying stuff based on its resale value in a year is meaningless if you're going to keep the item for a few years. You should buy based on the value of the item to you. That value is only partially in money terms. The rest of it is does it do what you want, what is the upkeep cost, can you add to it instead of replacing it, etc.
Yes, it is sometimes good to keep in mind the resale value of somethings, but in general when it's the first thing someone mentions, it tells me they're more interested in money and possibly status than the item they are buying. Now if buying used has been good for you, it's can be a good suggestion that a used camera will cost less. However, what if the person wants the features of the current camera? That means if he buys used, he's almost guaranteed to need to buy an upgrade sooner than later, thus costing more money than if he bought new.

Rant brought to you by being reminded of people who tried to save money and wound up spending a lot more in the long run. Especially when they had the money to buy correctly in the first place. And then they complained about it.
