Recent e-book readers akin to the 6" Onyx Boox C67ML Carta?

I broke my small Onyx Boox C67ML Carta 6" e-book reader. I am looking for one similar to it. I really liked that the Boox was "pre-jailbroken"—in other words, I wasn't locked into some Kindle or Barnes & Noble store, and I could easily install other apps. I also liked its capacitive e-ink touch screen.

What are some new e-book readers similar to the Onyx Boox C67ML that are <$150?

Also, I don't care about if it has WiFi or headphone jack, nor do I care if it has a front-light. I'm just looking for something cheap, simple, and reliable.

thanks
