Alpine's a good brand, used in certain high end cars too - I've seen them in Morgan's & Lotus (not to mention I got one in mine).
Bob, at $150 you've got a fair range to look at, it's the other bit's that start adding up, the interconnect from the unit's wiring harness to the car's, do you need a different panel in the console, installation costs. I minimised the last thanks to doing it myself but I used an ots harness adaptor and a aftermarket extra storage pocket to make the console look right. The last I needed due to going down in size from the stock radio.
