Thinking about buying a used Dillon 550b - I can't tell well from the pics but it looks like rust on top of the indexer, on the slide bar, some of the nuts and maybe some on the powder major. This is my first press (plan on using it very slowly till I am comfortable - going to remeasure powder every 5 drops or so). Supposedly the indexer doesn't rotate as well They are looking north of $400 I believe. Seems really steep to me considering refurb cost from Dillon.
