My very first transistor, I bought one mail-order, as I recall it was pretty expensive, something like $6-7, a kings ransom in the 1950's! I was super careful with that part and built a few different circuits all the while following all the handling precautions. I finally broke a lead off right at the base and killed it, but by then more transistors were available at lower prices.
