CIS and Bulk black inks for Epson printers

[jsheridan]

Who uses bulk inks and who has the best DYE inks.

I now have an empty spare set of carts for my 1800 printer. I'm using Jetblack all black carts from http://www.filmoutputsolutions.com/ and I'm wanting to re-fill my empty carts like this using the vacuum method

R1900, R1800, R2400, easyrefill cartridges for Epson printer

OR I'll buy some refillable carts. I'm looking for some good DYE based ink to refill those carts and wondering what brand others are using.
I've found a bunch of inks I just want to keep in the range of Jetblack quality as my films are perfect right now.

Been using MIS (inksupply.com) inks and empty carts for 5 years now or so. They don't make the easy
refill carts for my printers so its the syringe through the nozzle deal. No complaints ever, though I've
only used the black ink, no colors.
