Hikingman,
I very recently went through this thought process when my kinetics bullets puller "hammer" head broke off. I ended up buying the Hornady with collets for .30 caliber and .22, because they are the calibers I most often reload for in rifle.
For everything else, I bought an RCBS kinetics puller. Why? Because it will cover all the other calibers without my having to be a collet for every oddball thing I have. Also, RCBS warranty is excellent.
That said, I contacted the manufacturer of the kinetics puller I had that broke, Quinetics/Frankford Arsenal via email. Their response was "Send us your mailing address and we'll send you a new one." I did and received a brand new one in the mail, including a new collet set, in a few days.
So now I have the best of all worlds, a collet style for most of the stuff I do and two kinetics pullers, one as a backup in case the other breaks.
Regards,
Dave
