I have an Epson SX100 inkjet printer at home and am due to renew the ink cartridges. I've been thinking for a while about a bulk CISS system as I reckon this must be cheaper than replacing cartridges.

Does anyone have any experience of these systems, especially for Epson printers, or, more specifically, the SX100? Are the inks as good as Epson? Are there problems with leaks, spillages etc?

Are some better than others and if so, who would you recommend/avoid?
