How much do you want to spend and do you plan to remove/adjust various sights? I own both below. The NcStar is good and I have used it multiple times. It works but is a little more work than the Real Avid to get the slide in position and ready to use.

The Real Avid costs more but is probably the better value for me because it allowed me to remove the really tall front sight on my Springfield xdm elite OSP. The NcStar was too shallow.

I've bought other cheap $30 sight removers trying to save money on something I thought I would only use once, and to be honest I wish I had just got the Real Avid in the beginning. It is really easy to use and is versatile. It also feels like it will last forever. Just used it to put Trijicons on my PDP.

NcSTAR about $50 https://www.amazon.com/dp/B01HU4NNDE/ref=cm_sw_r_apan_glt_fabc_QKMF51910AMSEYS3YG33?_encoding=UTF8&psc=1

Real Avid $125 to $150 https://www.amazon.com/dp/B08BB6W9ZZ/ref=cm_sw_r_apan_glt_fabc_NCKXJSPNF8BZSP3EYWTR

I literally just bought one on Amazon.

This one also got good reviews:

And here's a very low priced sight pusher.
