When you plan on doing shirts - properly - bigger printer, bigger transfer paper and bigger press is better.
It also gives you better flexibility for future projects which inevitably come along and definitely come along if you are equipped to handle them.
As for printers, the Sawgrass is a glorified Ricoh printer labeled as a Sawgrass machine. When my Ricoh using Sawgrass inks crapped out, I was left hanging in the breeze. Nobody wanted to know anything about the problem.
A new Richo/Sawgrass 800 would cost me $2,000 + $300 (Canadian prices) for the bypass tray which would accommodate Tabloid Extra (13" x 19") transfer paper. So I researched alternatives.
My replacement is an Epson WF-7610 which takes the Tabloid Extra paper right out of the box, using Cobra inks in refillable cartridges.
Printer cost was $150. At that rate, I can buy 15 printers for the cost of one Sawgrass with the bypass tray. Inks are considerably less expensive and give equal results although the gamut appears to be somewhat different.
The down side is that it is a bit slower than the Ricoh/Sawgrass 800 and Cobra's color profiles need a bit of testing until you figure them out.
Also, with an altered gamut, it may take a bit of testing to match previous work with Sawgrass inks to new work with the Cobra inks, such as when working color specific logos.
As for all that other junk that Sawgrass calls a benefit to paying through the nose for their stuff, I don't need it. If you standardize your procedures and make notes of what works and doesn't, there is no issue.
