Don't really know much about the market. A lot of people want them, but you're not going to get a large sum per animal like you will for something like constrictors.

I think a rack system would be perfect for pacs. They like to be in dark, confined spaces, so I think they'd be appropriate. I'd want the same floorspace for an adult as you'd see in a 10 gallon tank, but you probably don't need the height.
