First off, please let me say I am not trolling for ebay hits. Just happened to come across this when I was looking up info about using decklinks with resolume.
I have an auction going right now for a vaddio hd-19 PTZ with HD-SDI card installed. Comes with remote and all.
Asking $2400 on a buy it now. http://www.ebay.com/itm/161025342775?ss ... 1555.l2649

I have used vaddios with resolume for a year now on a touring show. Work great, easy setup, great picture.
If you are looking for HD, this is about as good as you can get for a low price. The Panasonics are great but at about 4x the price.
