@northwestnotaryinc Great Question! 
Over the years I’ve purchased & utilized a variety of stamp brands & types; some oil-based inks, some water-based, etc.
The following are ALL reliable, crisp, clean impression stamps that I’ve utilized for my Notarial Stamp:
- Trodat Professional 5204
- XStamper
- Brother
- Titan
My current Notarial Stamp (and my FAVORITE overall) is the Trodat Professional 5204, while it’s a bit larger than most, it truly renders a Professional impression each & every time.
NOTE: Also, I do still utilize the other brands listed above for additional stamp purposes; i.e., Name, Commission Expiration, Jurat, Acknowledgement, etc.
