Digital BW, The Print

I've been reading a great deal about the problems people have had with
the MIS refillable cartridges. Now that the dust has settle somewhat
I'd like to hear opinions as to whether this is a prudent way to go vs
the conventional cartridges. I'm using an Epson 1280 and have been
using MIS UT2 and UTK prefilled cartdridges.

Thank you.
