ULTRA 3500 LINESCAN RECORDER

[RED5]

Hi all, just got a bit of information recently regarding paper for the Ultra 3500. Ultra no longer support the printer but a company called Codaoctopus use the same paper for their octopus 120 printer as seen here http://www.codaoctopus.com/printers/index.asp
Its certainly not cheap at £18 per roll with a minimum order of 10 rolls. Does anyone know of anywhere cheaper?
Cheers.
