If you can find one for $200.00, don't hesitate a moment - buy it! Think in terms of $500+
I like mine quite a bit, generally preferring it over the 15mm only because of size. I think the 15mm may be a bit sharper at the edges, but I can't confirm that as I've not done a side-by-side, head-to-head comparison. I've only used a 15mm a couple of times. Bruce used my 18mm on his istD, and I may have a few shots handy made under similar circumstances. The real question is whether you want to use the lens on a digi camera or a FF 35mm film camera.
