If you're ever in the market to get one, look for a boxed 200. Although the picture quality isn't greatly improved from the 100/150 (alas, who would be buying these for the picture quality :?: ), the internal LCD does make a big difference. It also looks nicer than the "binocular" styled 100/150.
I was fortunate enough to get one two years ago on eBay for $70 (the only thing it was missing was the external viewfinder, and installation disc). Look up "Christmas Conquest" on the forum search if you want more info on my 200.
