I've been using TonerTopUp refill toner in my Konica-Minolta colour laser for a good while. They do toner for the Brother printers. They also supplied a new fuse for the print drum when the counter disabled it and I'm now on my second 20,000 sheets. I get about 4,000 sheets from a refill.

I have two annual print runs of over 1000 copies, one of them double-sided, and inkjets just don't do that. Also, I've not had a smeared laser print yet - my inkjet prints have to be handled carefully, and are no use outdoors.

Colour prints are not quite photo quality, but are much improved using laser semi-gloss paper. The quality is excellent for graphics generally, and the other big benefit is speed.
