I got a DSO2100 from a guy in china on ebay for $200 delivered. As far as UK prices go this was really cheap but I don't know what that's like in the states. Its a two channel one and does everything I want. The guys ID is giorgio11185 and he also sells on US ebay if your interested. Generally experianced scope users frown on pc scopes but it works for me when checking engine management ECU's.
