I just did an internal hub Tikit myself:

I'm using a SRAM S7. Same range as the Alfine, easier to service, nicer drum brake (Alfine doesn't have a drum brake option, SG-8R25 does, but I prefer the SRAM one). I wanted a i9, but they aren't available yet. When they come out I may convert my other Tikit.
