I guess the more I think about it, the more uncomfortable I feel about it. The T1i wasn't replaced that long ago, so I guess I'm finding it hard to see NIB for that price. Plus the extras that add a couple bucks. If it's me and I've got a newly discontinued cam, NIB, I'm selling it for fair market value if I'm trying to raise money for an upgrade. I figure that's gotta be give or take the $600 range. I'm too lazy to look on e-bay, so that's only a guess.
Plus, if it drains your bank account, and you have to find a little additional money, you don't need the camera right now. Ask my 19 year old what happens when you drain your savings account to buy a much more expensive, but admittedly cooler shot gun, than you really need, and total your car six weeks later...
