The nice thing about Radeka's kit is it shows you how to make your own contact frame/carrier if you don't want to buy one. This is particularly useful for people who want to try it out but not necessarily invest in expensive equipment at the outset. The pins he sells are really convenient because they are large (not condit-type pins) and fit snug into the holes made by the 2 1/4" hole punch from office depot. I assumed the punch Radeka sells in the registration kit was some special device but when I asked him about it he told me which one to buy.
