ecbuyonline2008 on eBay has new Gaesori's for just a bit more than your $1k limit.
3C-Store has the Da-Yi 617 Shift II for about the same. I have one of the latter cameras, and can tell you that it's a really good camera! I started with a 90mm cone on it, but now mount a 72mm on it. A little heavy compared to my Xpan, but a great camera to travel with. I like the twin film pressure plates in the holder; keeps the film nice and flat.
