I just got a bonus and decided to try a single. I am looking at a Redline Monocog and I also found a builder on ebay with good feedback. The bike is a fetish with a manitou black comp and truvativ cranks. It is under 700bucks but I am not sure if I want to go with a full rigid or just a softtail. Are you guys running full rigid or softtail? I like the simplicity of the redline but the Fetish is a pretty sexy frame. I think the wheels are pretty decent but the brakes on it are probably crap but I have some avid mechs that will do nicely. Please share your opinions/ recommendations and let me know if there are any other good manufacturers in this price range. Any input is greatly appreciated. The item number is 7221650417 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=7221650417&ssPageName=STRK:MEWA:IT
