Yes, the hooks with 0.025" square pins should be easy to find. Searching for something like (tektronix,hp,agilent) (grabber,smg50) will usually give you some results of lots of 10 to 20 for a little over $1/each.

They are also often offered as complete set with the break-out leads. If you search for (hp,agilent) (01650-61608,pod), you will likely find complete sets of pods, leads and grabbers for well under $50.
