I have both the lyman oarnge crusher and RCBS Rockchucker, both are solid presses built well and will last a life time under heavy use with a little care. My rockchucker is early enough to not have the thread insert. Both have lasted for years with no real wear showing. I currently have the rockchucker mounted horizontal for sizing lubing bullets with my mecham sizer. The Oarnge crusher I use for heavy case forming operations. Both work great and are solid machines. But my favorite is the Co Ax.
