I have a Zeal60, and I like it a lot. The major reason is that it has LEDs on the board, instead of in-switch LEDs. Plus, it's purple. I won't be using it in my Revo case, however. Also worth noting that if you live in the US, after shipping a B.face will cost close to the same. Honestly though, they both are made well, and are very comparable.
I'm kind of surprised that only 91 units sold. I guess the price probably alienated more people, but what can ya do.
