If you can get a used Rockchucker for $40, vs the Lee at $63, get the Rockchucker. The difference betwen them is the same between enie and menie. Both good products that will last indefinately, given reasonable care. I'd buy the cheaper one, in this case.

I still ocasionaly use a RCBS JR, or a Le turret press, but the bulk of my larger quantities are done on a Dillon 550B. I got a great deal on a second used Dillon, so I will have one set up for large primers, and one for small primers.
