There are a few to choose from in that price range, but nothing I'd call high quality. Ebay has an asortment available.
This one, commonly known as the DWW-700M, is popular. Some have good luck, but I believe the motors use plastic gears which some have had issues with.
This is the lilliput motorized screen. As far as I know it uses plastic gears as well. I've read about a lot of quality issues with these, but some have had good luck.
This is a non motorized unit, but has left/right swivel. It is commonly known as the DWW-700H. I paid 275 for a new one of these on sale. It was pretty good while it worked. They have known issues with working at low temperatures (< ~45F). Mine broke under the 1yr warranty, but I can't get a hold of the seller (Armen, what gives?).
A little pricier, but better quality. Known as the K301 or the MTSVO-SC, I believe it uses metal gears for the motorized operation. They also are a little picky about the temperature, refusing to turn on at less than 10F or so (if memory serves). I believe someone found a bypass/workaround for this though.
For a 1DIN indash unit, there is not a lot of quality to be found. I'd say the Xenarc 700IDT is probably one of the best ones out there.
There are others. These are just a few I had seen around. Hope this helps.
