I, too, have the newer version. I paid about $90 for it because I needed it immediately to run some tests, and had planned to return it and buy the $50 version.
I will post some detailed scope measurements of the signal in a bit, but in the meantime, I figured I'd make use of my shiny new USB microscope and post pictures of all the critical components of this board, so you guys can get a better idea of what's inside. I can post pictures of the overall circuit board later (or you can use the ones above, which are apparently identical to mine). But none of the previous photographs have quality IC pictures, so I figured I'd contribute.
Although uploading 25 images on this forum is kind of tedious...
