Hmmm. I can't speak for the Z3 but I've a Z2 in what I pass off as the collection.
Being APS and not 35mm they often turn up for a pound or two in charity (thrift) shops and so I would not bother bidding for one but would just wait for one that's dirt cheap.
There's a few APS cameras that are worth having if only for the size to performance ratio*. My Z2 is a neat little camera about 3¾" x 2¼" x 1¼" with a x2 zoom lens, focus lock and centre weighted. It's a pure P&S but you can give it +1½ stops for back-lit subjects or snow and there's an infinity lock for shooting landscapes or through glass.
Mine came with the box, packing, leather(?) case, instructions and strap for a few coins. And it has a metal body, shutter speeds of 2 to 1/500 and all the usual flash options and data back options. Plus a self timer and an optional remote control.
BTW, it takes very nice pictures too and I've no problems buying film** or getting it D & P or scanned.
I hope this helps. I prefer it to the equivalent "iconic" Canon offering.
