Im still getting into the hobby, and have a real mix of stuff....mostly I checked out what the store had to offer, researched a bit, then made a decision based on my opinion, others opinion, price, and actually picking the thing up and having a good look at it....
I have a Lee safety powder scale.....it works, but I dont like it and am looking for something better.
Have a Lee Auto-Prime, works great. Gonna keep and use that for sure.
Have Lee case trimmer. Seems to be quick and easy to use, and quality is good on it.
I also have a Lee Auto Disk Powder measure........and havent used it yet, because I need the rifle chargin die for it......so am using my RCBS perfect powder measure. Just waiting for the stand I bought off ebay

I had a set of Lee dies once, and they worked flawlessly, but were fairly low on the quality scale. Have a set of RCBS now, and they are much better.....
My press is a RCBS Rock Chucker Supreme.....wanted that one so I dont have to upgrade at a later date

Unless I go progressive.......
