We recently added a UCJV330 Mimaki. We have a Roland XR640 which has been reliable for about 10 years. The Mimaki has been fast and excellent quality. We had a little learning curve with the new RIP software - none of us had used Rasterlink before. The machine does like to sleep and is slow getting ready to print (waking up, heating up). But if you wake it up before starting Rasterlink or sending the job to or from Rasterlink, then it is fast. The volume of work we put it through the last two months was significant and we think this was a great addition for us. Being UV, it does have some limitations - not stretchable for full wraps, not sure it is a good choice for perforated window film. But for decals, truck lettering/logos, etc., it really expands production. My favorite thing is going right to lamination after print - allows us to respond quickly to big jobs. The 330 is faster than the 300. That said, the prices on the 300 make that a bargain even new. Our sales rep sells both Roland and Mimaki and his advice right now has been that Roland hasn't made any leaps forward in a while - he keeps hoping they will with each new release. Hopefully Roland does something with their next release, but their current offerings do not out perform our XR-640 and that has a bit of age on it. My 2 cents, right now is go with the Mimaki, but then that is what we just did.
