Digital BW, The Print

Hi, I'm new to this group and I'm getting ready to by a new Epson
4800/7800 for my color printing. I've a 2 year old 4000 Pro that I'd
rather convert to B&W than sell for $400 (seems to be the going rate:).

I'm looking for advice on inksets. I've been reading at the MIS site
(UT-7) and cleaning cartriges, they seem to "talk a good talk". Any
advice on reliablity, clogging issues, leaking carts, etc., would be
very helpful. Or other brands on inks that I might consider??

Thanks in advance, Alan
