Main drawback appears to be that they are not full duplex... but at those prices, why not buy TWO?

Excellent idea and post, Tom.
I have posted two YouTube videos of the Baeofeng UV-3R being used for satellite work. I would suspect performance of the UV-X4 to be similar in nature. AC0RA and I have made a few "Baofeng to Baofeng" contacts to test the performance on several of the LEO FM satellites. Timing and antenna orientation is key and I would recommend two the radios be used for full-duplex, as in your suggestion Tom.
Here's a video of receiving AO-27 using the stock rubber duck: http://www.youtube.com/watch?v=aYZyC_vkew0
here's a video of receiving AO-51 using an Arrow: http://www.youtube.com/watch?v=oRN4uJXvnK0
(I did make a contact on this AO-51 pass, though I wouldn't recommend it because of the semi-duplex limitation)
