Thoughts on K40 Radar Detector

Ive been looking at a K40 system and its gauranteed to keep you from getting tickets for 1 year. If not they will pay the ticket. This has me very intrigued. VERY. Does anyone have this system? I have been a V1 wannabe for a year and was thinking about just going ahead and ordering it. But then I saw a report on the local Kansas city news that there is a radar thing thats still legal in kansas and missouri and they will pay your ticket if you get one. I missed the report so I dont know anyhting about it, and I cant find it on the internet. So I will ask you for advice, Specifically K40 vs V1.
