Di2 - Thoughts?

[Murf]

I'm starting to think about my next bike purchase (which won't be any time soon unfortunately, but I'm a dreamer! ) and I've been looking at some of the Di2 bikes.

Have many people on the forums got experience with riding electronic shifters? Either Campag or Shimano? I'm curious as to whether they are worth the additional outlay? Anybody riding a Di2 bike and decided they could never go back to manual shifting? Anyone disappointed with their purchase?

My next purchase will be my 'dream' bike, or as least as close as dammit I can get to it without the missus killing me. So I wouldn't be scrimping on wheels to pay for Di2\EPS etc.

So a choice between manual Dura Ace, and Ultegra Di2 and the thought is the Di2 as the shifting is flawless? Unless I need to save the few grams?

I had manual Dura Ace (well, shifters and derailleurs, not chainset\cassette) on a previous bike and the shifting was amazing. My current Reynolds 525 bike with 105, the shifting is not as nice, especially the front shifts.

This bike would be ridden probably 7-8 months of the year, and the thought of less maintenance and the self trimming is nice.
