buzkin,
They have been in and out of stock on Amazon for the past month or so. I had one on my favorites list, and some days they were available for $79.95. some days " Unknown when, etc." If you are not in a hurry I'd check back every few days. Maybe you could find one on Craigslist if you are in a big enough city for a large seller base. Other websites like Ebay might work.

The only difference I can discern between the two models you mentioned is the charge port. The older Rav like mine has the micro USB port, the newer Rav and the NewQ seems to list the USB C port. They may differ in the maximum size SD card they can utilize.

Edited: I just checked my local Craigslist and one is for sale near Seattle for $40, but that was posted a month ago. But, they do show up, so that might be worth a search every week or so?
