+1 on tumbiling with SS media.
(read thoroughly)
Lee pacesetter dieset works well, but I ended up shelving the Lee sizer & seater and started using the Hornady FL sizer and seater, and kept the Lee factory crimp die (best crimper out there).
Also consider the RCBS bullet puller (with matching collet) instead of the hammer-style pullers. Great for pulling down or correcting mistakes. Don't forget the Lyman case prep multi-tool to prep cases, scale, and a good caliper set. For trimming I use the Lee case length trimmer/cutter/gauge (pictured below)
