Don't feel bad. When I was just returning to cycling last year I walked away from a Raleigh 12 speed with Reynolds tubing for $15. I found out later, that bike was selling on ebay for $200 to $300. I had just picked up three old mountain bikes and was concerned about what my wife would say if I brought another used bike home. I just don't let those mistakes get to me, I now own over 12 bikes and don't pay attention to my wifes comments.
The reason I asked about the Technium is, I just obtained a virtual twin to the one on ebay only a different color. I'm in the process of cleaning and upgrading the bike.
