[Aavso-sid-list] Looking for strip chart recorder

[Frederick J. Wallace]

Hi,
I was wondering if anyone had a working, portable, inexpensive strip
chart recorder like the Rustrak for sale. I'd like to get one to use for
Itty-Bitty radio Telescope demonstrations to print out charts for kids
to take home (Kerry Smith of SARA does this and it seems like a great
idea!). Thanks!
