We've used Solaris for the past couple of years and they have been great. They had a problem a couple of summers back where the lever inside the cartridge wouldn't trip when the ink ran out, called them and they admitted the problem and told us to get credit from Fellars, which worked out great. Their offices are about 30 mins away from our shop, and I've called them with a couple of small concerns and they've even offered to come out to our shop. Great support. They do dry quicker, so you have to make sure that your machine is used daily.
