eBay is perhaps not a good place to go looking for a camera of any sort unless you can get a touchy-feely, up-close-and-very-personal inspection. Not meaning to tar 'em all with the same brush it can be handy: just beware of the bees, but take notice of the birds.

Lots of other goodies there can save a fortune over retail with all its taxes and imposts. B+W filters are one, but make sure you get a genuine one. I doubt very much the Real McCoy is $2.50...
