I was going to make a post describing how I populated what I consider to be an excellent loading bench on a budget, but decided to start its own thread.
entitled "Budget Beginning Bench you will never outgrow, for the novice handloader."
It describes you one can get started for $150 without compromising on the quality of the equipment (though you do compromise on the speed and convenience). When you upgrade, you don't have to lose anything
as you upgrade. (No trade-ins, just adding capabilities)
Please give it a read.
