I have used Lee tools for a long time and still use them at times. For a real quality priming tool the Sinclair is the one to have. Not cheap by any means, but will last a lifetime and beyond. I've had mine for probably 20 years and have never regretted it.
I have used the Lee, RCBS universal, and the Hornady priming tools. Sold the rcbs, I keep the Lee for a back-up. The Hornady and Lee have a good feel for seating the primers, but I prefer the Hornady.
I own the rcbs and the lee. The rcbs is more involved when you want to change shell holders. The lee is slick and works great. I grease mine regularly and it has worked trouble free for 4 years now. I have primed thousands of rounds.
I am another LEE user. I have 2 and they have over 40k squeezes on both of them. I have an RCBS hand prime tool that just sits in its box, it was not very comfortable at all to use.
I have used the Lee's for over 30 years also! Then I tried the RCBS table top mounted one and that is all I will use now.. use the same shell holders as there press so no extra shell holders to Buy and they dont wear out like the lee's do.
