Digital BW, The Print

Anyone here use Lyson inks?  If so, have you had any problems with
their customer service?

I'm expecting delivery soon of a used Epson 1280 that I'm considering
turning into a b&w printer.  The products I'm looking at are the Lyson
Small Gamut and their new Daylight Darkroom.  I've read conflicting
information on compatibility of the Daylight Darkroom product with the
1280.  To try and resolve I've emailed both the U.S. and UK offices of
Lyson and have had no response in over a week.  If this is SOP for
their customer service, then I'll look for another product.

Thanks.
