Has anyone looked at or tried an Evenknit Sock Loom or a Wonder Sock Loom?

These look like a nice tool for someone who does not want to learn to knit to knit custom hose. The pegs seem close together so that thinner yarn could be used or by skipping pegs thicker yarn could be used. Since they are adjustable some calf shaping would be possible as well as being able to handle different size feet easily.
