Does anyone know where one might find the newer type drum recorders.

I have a whole shed full of the old ones which move laterally as the 
drum turns,
but I've been asked to set up a seismic display in a public area and I'm 
just
not happy using the old drum recorders. 
And I think the giant pen motors I have... must be 80 years old... if 
not older.
