I know the expensive radar dectectors are really good (not ones from places such as Best Buy) and are less likely to get zapped. If you get one with a VG Guard of 3 or more with a 360 degree radius then you should be good, but be prepared to hear a lot of warnings from it even if Starsky and Hutch aren't on the same road as you are...

In terms of the ticket, definitely go to court, because nothing bad can come from it. The worst that could happen is that they don't plea bargain with you, and you're in the same postition you were in before. I have bargained my way out of 2 affenses now... once I kept my license from being suspended and points lowered along with 75% of the fine back, and another time with no points being counted against my record. Now, I just try to remember all of the speed traps I come accross for the future so I don't have to go to court anymore...
