As far as the older stuff.
The big issue right now is getting my freewheel fixed. LBS has basically refused to look at it. I talked to another guy who really did not seem to be very happy about being a bicycle mechanic (hey I didn't make him choose that line of work). But at least he would look at it. So my all of my rear wheels are useless at this point. The only replacements are the Sun Race free wheels which are no where near the quality of my Regina American Superleggera (eBay isn't much help - a quick check had that freewheel in the $450 range). Sun Race doesn't offer the same gearing. I can't cold set or spring that frame, so I'm locked into 126MM rear hubs. So my options are limited.
I can easily maintain what I have, but normal wear and tear will eventually lead to more of these issues, and I really don't have the time and energy to try hunting down what I would need keep that machine up to the standards to which it was built.

As far as EPS, I am only looking at frames with internal routing. I like the idea. Not sure if I'm really comfortable with electronic control. And with my luck, the year after I install EPS, they will come out with a version that connects via BlueTooth and not hardwired.
But that's all academic at this point.

Speaking of EPS, is it possible to connect both brifter *and* TT bar end controllers on the same machine? I would think it pretty easy to hack up some Y cables to make the connections, but I'm not sure if this is compatible with the EPS "Brain". Campy's literature on the EPS is dripping with CYA, so I'm a bit hesitant to go DIY on EPS.
