Michele and Terri, I did a search on the photo sites for this camera. I was looking at this one and the new Sony with the built in zoom, since I did not have a lens that fit any digital backs.
Mike pretty much convinced me that interchangeable lenses would be the best.
for $1630.00 from Butterfly Photo in NYC, I got the camera with the 55 lens, one battery, recharger and manuals - I think that was the basic which was 900.00 - then for an upgraded kit, I received another battery, set of filters including UV, polarizing and another, the zoom lens, another battery, a 258 quick flash card (most of these cameras fail to mention they have no memory included in prices), a lovely camera case and an added quick recharge ac/dc car adapter.
With the zoom on, the lens is so heavy my tripod droops now, so I will look at a new one of those. I hope I didn't forget anything. The Nikon Mike mentions has more megapixels, but you need their lenses. I suggest if you are happy with your SLR now, check with the company and see if they have or will be coming out with a digital version or a back with mounts for your lenses. Most are.

This is a great site for instruction:

Here are two more examples, one of color and one of sharpness.
