Stumbled across a reverse sensor by a company called Gearflag on eBay for about $70 with 8 (front&back) sensors, but I haven't been able to find any reviews on this product.

Has anyone actually heard of this company and can provide some feedback on it?

Not sure whether I want to install the kit myself or not yet, found a guide on 8thcivic that seems pretty good, but how much would it cost roughly for someone to install this kit (front+back+lcd screen)?

Thanks guys
