I have a mutoh, a Roland and a Mimaki. I have a sour taste in my mouth from Mutoh. It was an earlier model (before the Ultru inks came out). I had endless trouble with it, even with the ultra inks and finally bought a Roland 2 1/2 years ago. Besides from the Mutoh being a boat anchor (unable to consistantly print on vinyl without excessive bleeding), the supplier wouldn't help after the sale (even after BBB intervention). I went directly to Mutoh and all they did is say you have to take any issues up with your supplier. My experience with Roland has been the exact opposite. I have called them up and they have been most helpful in walking me through something. If you are looking at printers, trust me service is paramount.
I have only had the JV33 for a short time but I was apprehensive about not getting another Roland. I have had so many glowing referals from Mimaki owners that I decided to go with it. So far I am impressed.
The Roland so far has been the best investment I ever made.....
