I'm working on an interactive art installation and I'm looking for the absolute cheapest progressive frame DV camera I can find. It can be 24p, 30p, whatever, but it must be progressive, not interlaced. It should have a firewire output and that's about all I need. If anyone has a trashed camera that is still able to output a progressive signal via firewire, I'd be interested. Anyone know of any discontinued cameras that are fairly inexpensive? Single chip is fine--the cheaper the better. Thanks.
