Garment Vinyl For Summa Thermal Printer

Summa has the thermal transfer ribbons in it's DC4-SX printer/cutter. I like the fact there is no ink in the system. It looks like a good dual purpose machine HOWEVER I am having problems finding vinyl to print on garments, light and black.

This equipment purchase is designed to replace my screen printing and heat transfer shop. I am hoping to find a thin vinyl such as Siser Easy Weed. As everyone knows there is a very limited supply of transfer paper that prints on dark garments that does not have the feel of a Pizza Box. I am hoping the Summa will be the answer.

Any help will be appreciated to locate a quality vinyl suitable for garment transfer.
