I have a ti-83 graphing claculator, but would like to trade it for a ti-86. I accept that there is a price difference and I would be willing to include some $. If a trade is not acceptable, it there a place that will buy used ti-83s? -- This message brought to you by Colin Davis, His ISP, and the letter 'C' To reply to this message, please reply-to cdavis@thepentagon.com
