My 5155 cost me $20 (Canadian!) and I picked it up, so no shipping. I could have had a second one for another $20, but I stupidly declined. (I've always been anti-PC, but didn't know of the awesome clickiness of the keyboard)
Actually, it's quite useless. There's not much useful that runs on it and it's not as interesting as a Kaypro. I just like to keep it on my desk to click the keys. I like how the keyboard folds up easily, so if I need more desk space (for tea, cookies, etc.), I just fold up the keyboard.
