I agree that the underwater light looks cool, but in my area I wonder how long I would be able to enjoy it? For instance, right now my water looks about like chocolate milk....typical summer bloom in our ponds, with visibility around 22", and I can't imagine the combination of green light and brown water would be all that attractive.
So I guess that tips the scale in favor of the Bojo, for me at least. I do wonder just how much additional food the Bojo can provide, however.
