since i have the Elf II, and many problems with other tablets, i just decided to get myself a Nexus 7.
I can't get the service i would like, anywhere. I once had it for my V9000HDA (the person checked the screen and tested it, letting it run a movie on it for about a hour or two, no screen problem), but i think the place where i bought it from, is out of business now. Most places just don't care and send you a tablet with defective pixels, thinking the one getting it won't mind them...well when you spend that much money, you DO. And the big problem is when returning it, if you want to be sure they get it (tracking, insurance), you'll have to pay about 50$ for the return, and there's the waiting, up to 30 days.
I consider myself lucky to have an Elf II without dead or stuck pixel. A lot of China brands show so much promises and good features, but they all fail somewhere, most of the time it's in quality control, or the quality of the components, they always cut the budget in the worst places. And with Chinese tablets sticking with the same processors even if they are 10 inches screens...look what happened with the Nexus 10: awesome screen, super resolution, but the CPU and GPU aren't up to the task for such massive resolution! So imagine that resolution, but with less powerful CPUs and GPUs used by Chinese brands now...
But a 7 inches tablet is still too big when listening to music. It would be great to have another Nationite player for musics, small-sized, maybe with an AMOLED capacitive screen. i think AMOLED screens are cheap-priced (not cheaply-made) for small devices like cell phones now. and Capacitive because once you get used to capacitive screens, you just feel how much resistive screen suck afterward.
The one based on the Teclast T50 was very nicely-sized! the T50 8gb i had, i gave it to my then girlfriend, and somehow someone stole it from her...and later she also broke the SmartQ T5-II i sold her...and here i still have my old Samsung Yepp 256mb, still working, just the internal memory is way too small now, and lack of more audio files support.
