Need a review on RCA tablet

[marklbe]

Looking to buy an inexpensive RCA tablet to travel with. Features needed are USB and keyboard. Does anyone have experience with or could recommend an RCA tablet model?
I saw several models for sale at Wallmart; Cambio and Viking PRO, which is the more reliable?

Never heard anything good for any cheap tablet, RCA and other cheap tablets have a very high failure rate.
