Good printer to buy for a start up T shirt co ?

[Bruno]

I'm a designer setting up a T shirt company - I like the idea of sublimation as the print quality is great, no stock issues and it will give me lots of design flexibility.
I'm on a limited start up budget looking for a large printer and came across theses one. Having not actually put my toe in the water I wondered if any of you experts would give me advice as to whether these are potentially fraught with problems or worth the risk?

Many thanks

Bruno

This one can be easily converted for sublimation so the owners tell me
