I have a ~1 year old LI unit pulled off a car I sold recently. I can't count the number of tickets this things saved me from, probably well over $20k worth and suspended licenses, etc. I paid $800 for it when I got it and they retail for a little under $600 now, but I'll sell it for around 85BTC since it is used and has a couple scratches on it.
