Starretts are super nice but will set you back $ unless you can find used.

I've had a couple crap ones over the years & are basically a waste of money. Look for these typical issues
- Skinny, flexible handles. Typically too long for small tap range. Bigger tap handles aren't as much an issue as they have a predictable bite but for teeny taps use the right sized handle
- Poor fitting jaws. Too much slop in the clamping mechanism, usually loose QC. Screw clamp mechanism loosens up on tap after a few fwd/rev turns. Soup can steel jaws not up to task.
- Unbalanced which is typically non-centered head and or mass of handle screw-in clamping mechanism. It just feels wrong in your hand & makes starting the tap less joy than a well designed tool
