RE: New Aerial Video
It's the Aiptek DV 5100 purchased at Walmart for $75 dollars. Some stores are charging upwards of $100 dollars. It comes with about 5 minutes of built in memory so you will want to consider purchasing either a 256 or 512 megabyte SD memory card for it that will give you between 30 - 1 hour of recording time.
The Aiptek 5900 is a new model and can also be purchased at Walmart. It's a little taller and a tad heavier but I think it can do 640 X 480 at a full 30fps. The 5100 manages 340 x 248 at 30 fps and 15 fps at the 640 resolution. A great camera for the money, especially if you consider the image quality of a wireless cmos camera at the $100 dollar range.
