My reaction to belt sanders was the same as yours. I'd borrowed a
neighbor's contractor grade unit made it the 1960s and it was vicious.
Then, a few years ago, I bought a Ryobi BE-321 and it's one of my favorite
tools. Variable speed and a case that lets it be set down on the bench
upside down for use as a fixed sander.

I prefer the electric block plane for making scarfs in plywood, primarily
because I think it leaves the pores open, but the belt sander is a must
have. Yes, by definition it is an abrasive stock removal tool, but the flat
sole and the variable speed allow quite small amounts to be removed.

Tool chosen depends on the size of the scarf.
I've use both a router and a power plane, each with it's own jig to make a
lot of scarfs on pieces less than about 6" wide.
If sheet goods are involved, then the Gougeon Bros have a neat attachment
for a circular saw.
I would do most anything to avoid a belt sander, they are strictly a PITA
except as an abrasive stock removal tool, IMHO.
