Well, I'd like the unit to cost as little as possible, because I'll
probably be making a bunch and giving them as gifts (very expensive
gifts). I might try to sell a few on eBay... considering the ones on
the webpage sold for $400 each, preordered (for 6-8 weeks in the
future, which is about now). So a pump under $50 would be great.

Look at model railroad accessories (like Faller or Vollmer). ISTR a tiny
solenoid pump that ran waterwheels on some models.
