Hey Mundlim,
I think Riso is a bit an underdog in the UK, but they are very big in the Asian Market, just not an MFD we see so frequently in the UK.
Regarding switching from Laser to Inkjet it really depends on what you are using the Devices for. One good thing about Laser Printers are that you can use highlight markers on them and the Print doesn't smudge, whereas with Inkjet you get yourself in a mess.
Regarding cost per page the Lasers usually win, but interesting to hear that they offer a lower cost per page.
As for PaperCut, they work with all major Vendors, and are compatible with Riso, you can even get embedded licenses if you opt for one of their bigger MFD Models:

Hope this helps.
