A S&G combination lock can be had for about $100. If you buy one used, you may need a new dial shaft as this is cut to length during installation, and you will need a new spline key to complete the installation.
Avoid the S&G 6741. It has a wider tolerance (+/- 1.25 rather than +/- 0.5) on each digit and uses Zymac (a turd polishing name for a cheap zinc alloy) rather than brass wheels. The 6730 is the workhorse Group 2 S&G dial lock. The 6630 is the 2m version - a bit more complicated internally, and has the Group 2m rather than Group 2 rating. (Yeah, I know the S&G site says Group 2 for this lock, but it's 2m unless the rating was downgraded).
Just make sure your safe uses a retracting style bolt rather than a swing bolt before replacing it with one of these.
If you safe uses a swing bolt, Securam makes an interesting lock that combines electronic pushbutton access with a reundant dial mecanism. (Actually, I recognized the linguistinc goof In that sentence, because Securam still makes this lock no matter what kind of bolt your safe uses).
Always make sure your safe handle is turned all the way to the unlocked position (counter clockwise) so the locking mechanism will not rest against the bolt. The prevents "bolt side pressure" that causes additional strain on the motor that retracts the bolt.
Thanks for the info. I'll let him know as it's my bosses safe. I have a superior regal safe with no issues myself.
