I've had the Smarttop for over a year now and love it. Bought mine used off eBay for less than 150. If you hunt online, you can get a good deal on one.

Just remember that when the window is cold, you have to chop it...I use a towel given to me by the original owner...But on a hot sunny day, once the window warms up, I do not hesitate to drop it without stopping to do the infamous "chop"...
