Help needed buying an Android tablet

I am looking to buy the following tablet:7Inch Android 3G Mini Laptop Netbook E-Book - DinoDirect.com. I have been told the processor is really slow,(VIA WM8505+). Can someone help me out?

Thanks in advance!

 

Hi there
I bought the Witstech - wits A81E/G, its a great little 7" tablet and comes with all the tools, Andorid market, apps. with a removable battery makes updating fireware a doddle.
And I mean a doddle I am 63 and did it just fine and fast. If you go to this site there is a manual there PDF :-http://www.retailgadgets.co.uk/ dont use there firmware a newer one is available on the wits site :- ????????!??A81 MID??????????? that includes all the proper stuff for this tablet.
Mine now boots faster and appears to work quicker. Google, wits A81 I am sure you will find a seller locally mine was in the UK as I live there.
Hope this helps, take care, bye
