Using cast iron is definitely a bit of an art form. Once you learn it, it works great- lots of good vids on youtube demonstrating the process. I like cast iron when I want a slow diffusion of heat (cast iron is a bit porous and acts as an insulator to some degree). When I want a quick transfer...
The old Singer 431 series were, still are some of the best all round machines ever made. There are many in excellent shape for cheap at auctions and garage sales, plus lot's of spare parts/accessories to be had on online. They can be tuned up/rebuilt almost indefinitely- something that can't be...
