I should probably clarify something, we got the cheap tablet because I didn't want my Nexus getting broken. But I guess one could consider the Nexus 7 a cheap tablet as well. And if that's the case, then I very highly recommend it. Yes, there's no SD card which is more or less the biggest thing, but I've been lucky enough to not need it.
And, more importantly, Barn the Younger also recommends it and actively preferred the Nexus 7 over the Prestigio.
