I have a Da Yi that I picked up for about $400 (new) on Fleabay.
Very basic, robust, but a bit awkward to use.
What I do like is the fact that I retain all the movements of the view camera. I would not consider a panoramic camera with at least some rise/fall capability - unless you are happy with the horizons being smack in the middle, or curved.
I also upgraded a couple of lenses - I noticed that sharpness fell off at the ends of the image even stopped down.
