Hi Shane,
I run a Fast T-jet2 that I bought 2-3 years ago now. After switching to Belquette bagged white ink (CMYK is still bottled), we don't have any troubles. It has been a work horse and has made us pretty good money.
If I had to do it all over again here is what I personally would do now, knowing what I know: I would buy a used T-jet2 or Kiosk II used from eBay and fully refurb it myself. But that is just me, not to mention I am very mechanically and electronically inclined.
If you are in the market for a brand new machine I don't have any experience. But if I had a lot of surplus money and were looking at new I would look toward Brother DTG machines. The reason is because their machine is all of their own technology and not based off from Epson printers. Don't get me wrong, Epson makes the best printers. But to purchase a brand new DTG machine then I would look for something that is TRULY commercial grade and not a dissected Epson printer put into a new shell. Kornit is another one that comes to mind, Epson based?.... I don't know.
Just my 2 cents worth!
Good Luck!
