Farnell stocked some of their gear when I last looked.

While a paper strip recorder might have seemed a good idea back in its
day, actually using one in this day and age would be a rather obvious
waste of paper.  The kind of device you're looking for is called a
storage oscilloscope or data logger, these days, mostly depending on
its typical sampling rate and number of channels.

Any computer or PDA with decent sound hardware should suffice for a
working, no-cost, software-only approach.  Just connect your analog
input to line-in (adapt level and impedance as needed), and record
your signal as an audio stream, which you can later transform into
whatever kind of plot or display you like.  It won't be spectacularly
accurate, granted, but it'll still outperform a paper strip plotter on
all practical counts.

I've used http://xoscope.sourceforge.net/ with a PCI audio card and got
good results, but never quite come across a chart recorder.

Go to http://www.dataq.com/194.htm

For $50US, you get a 4 channel, 10 bit A/D converter (serial interface
to PC) and PC chart recorder software.
