Down to $250 nowadays (was $400-650 on sale a year ago)... tempted to get but I would lose some features with the car... what do you think? Do you have AA/ACP in your car?

I just run it on my phone. I have a suction cup bracket that sticks to the windshield and I place it at eye level, just above the dash.
By getting used to using the phone app I can easily move it between cars and into rental cars.
