I got my order today and they are very neat, IMO. Like quinnnchick says, the really dark color doesn't last that long all the time, but they definitely stay colored to some degree until they hit the ground. Some bubbles are darker colored than others; it'd probably help to shake up the bottle first, but I didn't think to try. Didn't have any leaking problems, though, and they definitely don't stain. The flecks on my shirt have already disappeared in the last 20 minutes.
Worth $20? Probably not, but I don't mind spending a bit of money to support what I think is a neat example of scientific research. :-) And besides, now I'm the only kid on my block with colored bubbles!
I'm certain that as long as they're popular enough to make some money that production will increase and price will drop, and we'll undoubtedly see them in brick-and-mortar stores before too long.
