The right answer is you don't give enought information.
What color garments are you printing on? If you don't need to print on dark shirts and have no need for white ink brother comes highly recommended for quality and service.
If white ink is needed...and if you intend to do a high volume of garments and can afford $100K. to $200K. you probably want to look at Kornit. If you want a well engineered unit look at the Flexi-Jet. Especially read the FAQ on Flexi site and you will see that having the print head move is better than the platen that holds the garment. T-Jet has probably sold the most units but (and maybe consequently) has the most horror stories.
I have a personal problem with the company that markets DTG so take this with a grain of salt. The HM1 the more expensive unit that they sell prints a narrower field then Flexi. and is not based on as good an Epson Print driver as the Flexi. The Kiosk, their cheaper model is probably prefered if you are doing very low volume and need to get low priced unit.
Few people will come right out and recommend a unit. They give the sage advice, go to shows to see units in person, and get samples. I would add wash the samples before you judge.
In the end you may probably find that pretreament is more important than the printer and machine maintenance is the only path to avoid buyers remorse, regardless of printer
I found out that today that my lease will be approved. Can you guess which one I'm buying?
