Just had a quick look around, Raidentech had a special: 4 for $152.78 ([link=http://www.raidentech.com/1wolarecorcb.html]link[/link])

They are the older ones (like mine) - they have done a re-release, different paint jobs, same mechanicals (and therefor same performance). [link=http://ca.youtube.com/profile_videos?user=RunningCat1]RunningCat1[/link] has some videos on Youtube - you will notice the tracks make it get all out of shape, especially on turns which are laborious due to the laggy drive system (small 9.6v battery, non-proportional, single speed, slight pause between go/turn commands - coupled to the nasty joins in the tracks = disaster)
