Yeah, I checked eBay. There are 2 that are new, and the best offer from one of the sellers was $450 with shipping.
There are a few differences between the III and the II. The III has a 20mm lens, and a few features that look like they would make it easier to use; the focus has two options - infinity or 2 feet, the aperture control knob is on the top (instead of the front on the II), a target light, and there is a flash control knob on the back panel. The III is also rated for 200 feet vs. 160 feet for the II. They're cool features on the III, but not worth spending that much more than the II, imo.
Anyway, thanks, I'll wait and watch for one to hopefully appear for sale there.
The YS-90DX looks cool. I think I'll look/wait for a III for a while, and may check to see if the YS-90DX is still available when I find a camera. Thanks
