I would be open to that option. Assuming I wouldn't be prone to false-tripping due to various garage loads turning on an off while I'm brewing?

I have a Siemens 50A double pole GP-type in that slot? What is the cheapest replacement?

I'm seeing $100+ on the breaker vs. $56 on the spa panel w/ breaker

I went to an electrical supply house that sells both wholesale and retail and purchased one for my Siemens panel for about $85.00 a couple of years ago. Look further than just at big box hardware stores.

If you aren't having problems tripping your existing breaker now you shouldn't have problems with a GFCI breaker. If you do have it trip on a ground fault then you have some equipment that should be investigated for grounding problems.
