It would be great to see that 3rd tier OEMs can access the Google Play store. I have long wondered why Google would shun inexpensive tablets. Android can accommodate lo-rez screens and slower CPUs pretty well, and existing automated tests can verify compatibility.
The $59 device has a PDF for installing an alternative store so maybe they've made a similar error? (http://www.ematic.us/sites/default/files/Installing1MobileMa...) The quickstart guide shows some other app store. (http://www.ematic.us/sites/default/files/EGL26BL_QSG.pdf)
EDIT: the manf website for the cheaper device is horrible. Here it is (http://xeliotablet.com/) they have a faq about the play store on there somewhere.
