I think the cheapest IR port available is likely the 17BII (original gold bezel from the 1990s and early 2000s). Average strike price now with shipping is usually under $25 USD. (post covid inflation adjusted numbers). Can't do much with it other than print.

The HP 48G/G+/GX has the ability to control the IR output with a little more fidelity. I used to turn on (and off) the CRT TV in a high school class room at a rage of ~7m using my HP 48G and the brilliant Remote program. The teacher thought the TV was broken because it would only ring from the CRT and never actually display anything.

If I recall correctly, only the receiver element was handicapped to prevent cheating on tests.. the transmitter seemed to function at a decent range, depending on what you were doing.
