Bearzilla,
That hub is cheaper than the one I had found. The clean and easy 3 speed hub would be nice. Of course, you still will need some type of jackshsft setup. Please keep us posted of your progress. I have not yet seen any postings of anyone actually useing one. I hope you do, and I hope that it turns out to be reliable.
If it does, I'll try one myself but I'll use a thumb shifter.
Also let me know if you have any problemes getting the hub laced.
Good Luck
