[Highland Park] Looking to buy ipad 1 keyboard

I was given an ipad 1 by a friend and while i find it super useful, i REALLY want a plastic (not rubber) keyboard for it. I write long emails and this onscreen keyboard is too tedious for words (pun intended).

A keyboard/ case would be ideal, but at this point i'm willing to settle

for the keyboard.

I spent a couple of hours searching online and becoming confused and

decided to put it out to our list serve. Have you heard/read anything that might be useful to help me buy one? Thanks in advance, PAM
