I have a Ricoh with Sawgrass inks. The biggest benefit is the gel inks which basically prevent the heads from clogging and when they "clog", a simple cleaning takes care of it. My machine is old enough to have the Ricoh badge (they're rebranded now as Sawgrass, and have been for several years).
If I were to buy right now, I'd probably buy another one, but I'd seriously consider an Epson simply because they can print 13x19. The cheap ink really doesn't matter much to me. The work I do doesn't use a lot of ink. With Epsons, you still have to worry about clogging. The printers themselves are cheap enough that they're almost disposable, but it's still an inconvenience when your equipment all of a sudden stops working.
I am seriously considering a UniNet 550 or 600 now. Being able to do garments of any color or material is a pretty big plus and would open another market. I also like I can do acrylic, wood, metal, and wood with white ink. The price is also way more than the above options, but is a good bit less than a UV printer, and also is a relatively maintenance free option.
