Well it's hard to find the differences just by looking at the spec sheets. Here's a handful: larger frame (good for my large hands), more rugged body, pentaprism vs. pentamirror, can control speedlights wirelessly, greater shutter speed range, faster burst, different control layout, LCD screen for the settings so you don't have to have the main LCD on all the time. There's a few more differences, but i can't think of them right now. That right there is worth the $200 more to me.
Thanks for the battery advice too, i'll look at picking up a spare. Hopefully Adorama can knock a few dollars off the price then too. Not counting on it, but i'll try.
