Yudu Screen Printing Machine

Has anyone here ever seen or used on of these? What are your thoughts on them? I'm looking to do some screen printing on t-shirts and was wondering if this is a worthwhile product. I will mainly be doing two or three color designs, nothing too fancy. Please let me know what you all think. 

It uses waterbased inks that if you set them properly (using heat like from an iron) should wash just fine. You may have trouble getting bright colors on dark fabrics because the inks tend to be somewhat translucent. The consumables for the Yudu are a lot more expensive than regular screen printing systems. The Yudu also does not lend itself well to mass production. You can use it for that, but you have to kind of wriggle around the platen design.
