I use a Freedom Mini Bluetooth Keyboard. It has all 4 sets of keys, a 4 directional tab (arrows), an Escape button, and most normal buttons. The only problem is that you have to hit the 2nd key (Num) to access characters such as comma and period. But ALL letters are typed without the Num key. It's $60, but I got a new one from eBay last week for only $40
