I pulled the trigger on a Shimano Alfine 11. This deal just seemed to good to pass up:

Amazon.com : Shimano 2014 Alfine 11-Speed Internal Bicycle Hub - SG-S700 : Bike Hubs : Sports & Outdoors

If you look closely, there is a vendor in the US selling it for US $252. A tiny part of me is saying its too good to be true, so we'll see. If the deal ends up failing, I'll seek out that S-A 5 speed. Something about the S-A units keep me intrigued and thinking it represents a sweet spot solution for many IGH customers, and certainly it has an attractive price, relatively speaking.
