I just had a back up system installed last week.
Sensor (drill in type) - $60
Paint Match - $100 (I got it done for less, cuz I know the autobody guy, but he said it would be around $100 for other folk)
Install - $80
Total cost = $240
Most sponsors could not match that (on RS or bcmazda3).
Got it done by a guy named John. PM me for phone#.
The install was very clean, can't tell where the wire is unless you really look. The guy says he's been doing it for 10+ years (i exercised professional skepticism

) and does install for dealerships. Overall he seems to know wtf he's doing. The only issue I had was, my A-pillar cover was lose, going this weekend to get it fixed. Unit comes with 1yr warranty.
