I bought a lightly used Schwinn Super Sport DBX off Craig's List this Spring. It's has been a great bike for commuting....I have a rural commute of 34 miles a day and decided at the end of last year that I should upgrade my ride from the Trek 820 MB I was using. I've got light's, fenders, rack and even a flasher flag on the DBX and it has been working great. I looked a trek XO-1 last fall but couldn't pull the trigger on the $800 the guy wanted. If you're patient CL is a great place to get a good deal on a commuter.
