Hi Berni,

I used nothing but modern automotive fuses*, in fuse blocks similar to this one:

They come in various sizes, from Digikey and B&C.  Since my flight test phase, I haven't blown a single fuse in six years and 600 hours of flying.

My fuse blocks are inaccessible in flight because if the fuse blows, there is most likely a problem that I'd rather troubleshoot on the ground and because no single fuse can take out enough stuff to be more than an inconvenience.  I believe the idea of resetting circuit breakers came about because way back when airplane manufacturers unintentionally undersized some breakers, causing occasional nuisance trips.  I've designed my electrical system to avoid nuisance trips.

I have a couple large fuse blocks on the avionics shelf and one near the battery, behind the pilot's seat back.  They are cheap enough that pretty much everything has its own fuse.

I think fuses versus breakers is a Ford versus Chevy sort of thing.  Either one works fine.

Best,
Dennis

*I have two circuit breakers; one for the overvoltage disconnect for each alternator control circuit. Neither one has ever tripped.
