I know of a brand that I was NOT happy with, it's the Pandigital. I bought a refurb one for my grandson and had problems with it, tried to get it replaced by Pandigital, only to find out that they are now out of business and no longer supporting them or honoring their 90 day refurb warranty. So, I'd stay away from those.. even though they are very inexpensive now.. that's why. I was able to get a refund for it from who I bought it from, but I just wanted this inexpensive tablet to work.
I have a Toshiba 10 inch Thrive and it's wondefull. Look at those, they are reasonable now.. around 200.00.
I'll be watching this thread.
