I bought two el-cheapo cobra radar detectors on fleabay for under $25 bucks each (one 14 band, the other 15 band). The 15 band goes in the XF with the mirror mount mod and the 14 band goes floating between the truck and the Camaro. I got these after a 89 in a 60 ticket that could have set me back a whole lotta $$$$$. Luckily, the female trooper wrote it 9 over and then we negotiated it at courthouse for court costs of 30 bucks. So, these have saved me many times already. IMHO the higher priced ones are just much ado about fluff and not worth the added $$$. My $0.02 cents worth!
