I am curious about this as well. We have been using the DTG Viper for almost 5 years now and I am getting nervous as it is starting to have various maintenance issues (1001D errors fairly regularly). We switched to Firebird ink and pretreat and are very satisfied with the vibrancy, overall print quality and the cost ($150 per liter colors and white).
I like the idea of the perceived ease of maintenance but am concerned about the sacrifices I would need to make (printing 1 shirt at a time, higher ink costs, equivalent quality and etc.).
Curious to hear from anyone who switched from a Viper or other similar DTG printer to the F2000.
