I have a Lee and it's a POS, as with pretty much all Lee stuff, all crap. It would flip primers on the side all the time. Personally, I do not see what the big deal with the Sinclair is. You have to handle each and every primer individually. There isn't too much magic in seating a primer. I just don't see the sense of paying more money for something that is going to slow you down.
I use the RCBS APS strip loader with the CCI strips. Unless I was on a quest to seat every primer to within a very fine specified tolerance on the seating depth I couldn't think of any reason to use anything else.
I have used both the lee and the rcbs universal primer. They are pretty close, but i actually liked the rcbs universal primer a bit better. I ended up getting rid of it though because it was not truly universal. I could not load 5.7x28 shells with it. Loading 1 primer at a time seems like a pretty big pain to me. The lee works great for the money in my opinion plus the shell holders are cheap.
I had a lee and it worked alright till I broke the handle off.
so I bought the hornady one and its SO much better than the lee. I couldn't get the lee to seat the primers consistently in the primer pockets. The hornady is so much easier and smoother and works with any brand of shell holder even has different primer trays for shell holders that may have different sized holes in the center. so it sounds like anything is better than the lee. don't waste your money on the lee
