Spent all evening doing Shimano workshop courses. "Certified" in Di2, Dura-Ace 9000, Ultegra, and XT component groups. I get a bunch of nice shiny certificates to hang up and EP sweetness. I'm sold on Di2, also. Ultegra Di2 looks to be great for the money. Now to come up with the funds for a U Di2 Felt F3... The Shimano modules are so annoying and I'm only half done.
Also snagged a Paul Components high flange front hub off of eBay for $48... no idea what the heck I'm going to use it for, though.
