Just this week I got my sublimation setup running.
The Epson purpose-made sublimation printers f170 and f570 appear to be excellent choices with easy color management, affordable supplies, and good reliability. Unfortunately, the f170 has a maximum print size of just 8.5" x 14". The big brother f570 is a $2500 110 lb 24" monster. There's no Epson purpose-made sublimation printer in between those sizes. Also, I only have a 15" x 15" heat press so the enormous print area of the f570 is wasted on me until I upgrade the press, too.
I ended up choosing the ET-15000, an Ecotank printer with a maximum print size of 13" x 19". I'm using 3rd party inks and paper--a few good ones seem to be available but I chose InkOwl. My research has suggested that this is a pretty reliable combination. Cartridge-based printers are apparently much more of a hassle when converted. We'll see how it goes.
So far it's pretty cool. After years of weeding vinyl and thinking about designs with few colors, being able to transfer full color onto various surfaces... with no weeding... feels like cheating. Lots of cool blanks are available.
These are just my first tests, clip art on cheap neoprene coasters. My color settings are off, still working on that.
I was really surprised at the level of detail. Very cool.
