I got a US dealer on Ebay with excellent feedback (eurobikeparts) offering me a brand new full group DURA-ACE Di2 9070 for $2500 (without the brakes since the Madone 7 has them built in). He also has full Ultegra 6870 Di2 for $1320 or DURA-ACE 9000 Mechanical for $1300. I think the Di2 will be the best investment if I end up selling this bike in a few years. I'm thinking the 9070 would be sweet on this new ride-already have the 6700 group on Craigslist. If anyone on here is interested, shoot me a PM and I'll give you a deal
