I bought mine online at Kohl's as they had it both on sale and were giving additional store credit. The sale price was $120.00 and included shipping. There was also a 15% off that for several days, and $10 gift card for every $50 spent. I only got the 7" so I don't know what the price is on the larger one, or even if they have it.
As for the unit itself, it has a short battery life. If you are mostly at home and can use it plugged in, this may not be an issue for you. Mine came with wifi and bluetooth.
There are limitations.It does not come with Google play market. With googles recent changes, the calendar that it comes with , can no longer sync to a gmail calendar. I confirmed this with Zeki support, which had an Asian accent that was unusually (for me) easy to understand.
It is inexpensive.
It does come with an internet browser, camera, aldiko bookreader, amazon app market as well as socio app store, front facing camera (still and video) , music player, sound recorder. The settings allow you to control things like the brightness, font size and text to speech output, etc. It accepts a micro sd card.
If you can make do with a 7", maybe connect to a larger screen tv? Then you might want to check around for sales or discounts. You can join ebates for free and get a small percentage of your purchase price back every couple of months. If you are watching moneys , it is better than nothing. July 4th is coming up and maybe it will be on sale?
I have been told it will also do skype.
