You might also want to consider a Canon 30D, they're a steal now at $800 new (B&H). I've been shooting with one for a little over two years and am very happy with it. You could learn to shoot with it, then if you decide to upgrade you could sell it with less depreciation than a newer body or you could keep it around for a backup. This would free you up with more money for lenses.
Good luck with whatever you choose.
