If you look at the 22mm Harken block, you'll see an example of a design
that is difficult to jam - the pully rim is even with the frame of the
block. Agreed that they're relatively expensive at $10 or so each, but I
have never had a pulley jam. These are designed for sailing where a jam
could be a true disaster.
