It's a good deal, but no way is it over $1000 worth of equipment. I did a few sums based on eBay UK prices: you could buy the camera and lenses individually for about £150 ($230); the other bits and pieces could probably be purchased for under £75 ($115) individually (assuming the filters are reasonably good quality).
So, that's a discount of $195 on around $345 worth of gear… a nice bargain but nothing extraordinary.
