I bought the screen print kit. So far I have done two screens. One I did single color and the other I did some masking to make multicolor. My alignment was off on the multicolor but that was my fault. 
The kit makes the process very easy. About 30ish years ago in high school I tried this process and it was very lengthy and tedious process just to set the screen up. 
If you are looking to screen print, I definitely recommend this product.
