I believe the Schaller with 45 degree tabs fit as well.
John's version are really cool and fit the PRS vibe best.
I really liked the functionality of the Grover 406. If you don't like the little kidney bean buttons, Hipshot buttons will fit and they come in a bunch of different styles.
Make sure you get the nut sorted out as well. If you ever hear a pinging sound when using the trem or tuning, it means a string is hanging up and will have tuning stability issues that tuners won't solve.
Like everyone has advised you already, send in your tuners to John Mann to modify to locking tuners, or buy the hipshot locking tuners with ump. No modification needed to install either.
What John Mann tuners fit a PRS SE 245?
