Back in my Roland days I used the same style bulk system as brightbanner does.
These systems are only a couple hundred bucks or less, and if you have to get chips, you'll probably spend less than $250, plus inks of course. Plenty of places sell them, you can even get them on Amazon today. Easy to install & set up. They have provision for chips, I just used ones out of old Roland cartridges (some will work with those, if yours won't, permanent replacement chips are cheap). I liked the nice wide cap, easy to refill, you can see how much ink you have left with the translucent models (some are black, so you have to open them to check levels), they come in 4 color or 6 color configurations. I used these for years in multiple Roland printers with Solaris inks, and never had any issues.
