I feel the same way. Can't stand having my bike at the LBS more than a few days.
My wife now wants me to get rid of my old Cannondale now that I have the Redline. Granted the frame is a bit too small and it isn't very comfortable on long rides. And yes it is old, outdated, and needs work. The practical side of me wants to get rid of it since I never ride it and it just takes up space. However the sentimental side of me doesn't want to sell the bike I purchased new back when I was 17. Ugh.
