I've heard great things about the GCW Zero consoles. They appear to be easy to develop for, well built, and long lasting. Which is more than I can say about a lot of devices I've seen sprout up over the past few years.
As for me, I had a JXD 7300, but sent it back to the company because it was problematic.
With a little bickering, I was able to get a JXD S7800b back instead, which from everything I am hearing, is a major step up from the 7300 featuing improved specs, better design, and high compatibility. Apparently I can run both Dreamcast and PSP on it not to mention DosBOX at very high speeds... that's a sale to me.

I looked into the JXD S7800b from

If all else fails, I can surf and watch my Netflix with a decent grip on the device.
