hello all

looking at getting two cheap tablets for the kids and getting rod of their nintendo ds
I dont know much about them but would like to be able to root/hack it so i can put a better built rom on it.

I am looking at these, could someone who has some experience suggest which one i get

eBay - The UK's Online Marketplace

eBay - The UK's Online Marketplace


one of these says dual core, not sure if that will make a big difference or on of them says it has 512MB of Ram which i think would make a difference


thanks in advance, if anyone thinks i should maybe get something else from else where then please post me the link

thanks
