Save money or buy tablet?

I've asked this in a different forum, and I've received no replies. I'm asking here, since my time to purchase these is running out. It's not like I have to have a tablet...but I'd like to hear opinions.

I am debating between getting:
Samsung Galaxy Tab A 7" ($69.99) example here
Azpen A780 7"($44.99) example here
Azpen G1058S 10.1"($89.99) example here.
Azpen X1060 10.1" ($99.99) - can't find any ad for it online. I only found a few negative reviews. Also, I only know it is a Windows tablet, 2GB RAM, 1.5 GHz processor, 32GB memory/internal storage.

I'd like to get a case and keyboard with it, but specs matter first. Also, I can't return any of these once I buy one. Furthermore, I've heard that it's better to get a Windows tablet rather than an Android...but I'm not sold on the Azpen X1060, since I don't know the exact specs. I've heard that Samsung tablets have Wacom pens too...so they are as good as Wacom drawing tablets (which would be a plus for me!)

 

Have a look at the rca windows tablet with included keyboard at Walmart. Can return it then if you don't like it.
