Looking at ZSK

Hello,
I am new to the embroidery world... Sitting in the Chicago area. I would like to start up a business and already talked to a few friends. For what I am planning to do they recommeneded me taking a 4 head and 1 head machine - basically individualization of clothing... i have heard some good things about ZSK. I looked at their website and it looks promising. Any thoughts about their SPRINT machine? One thing I want to do is embroidering shoes and they seem to have a solution...
help for the right choice of machine is much appreciated

I live and work about one hours drive from their factory here in Germany. Very professional and helpful people. Their embroidery machines are in the same league as Barudan and Tajima. ( Only my opinion. ). Only down side is their electronics and that they are a little noisy.
But it will useless if you have no local support. Whatever machine you buy you must have a helpful supplier to help you over the first years of using and learning the machine and embroidery.
I often go to horse and dog fairs. The Sprint is the most common machine in these fairs.

PS I have Barudans.
