I have a Herotab M10 that I've been thinking about selling...the tablet in the link is actually the second version, mine doesn't have a camera but I think that's the only difference. If you are interested let me know and we can discuss it further.
I have an ASUS TF101 with Keyboard as well. Except mine has a bent bracket around the charger port so the only way to charge the tablet is through the keyboard. Minor inconvenience, but it'll lower the price I'll sell it to you for!
