What tool are you guys using? If I wanted to start rounding up tools to tackle a rear end rebuilt, what size bearing seperator should I get to use with a shop press? Thanks!

This is the one that I use. It's a cheap HArbor Freight part that I bought over 20 years ago. I keep telling myself to get a better one, but this one keeps working. It's pressed of about 1,000 pinion bearings.
