Oh c'mon..
That depends a lot on the engine. I thought he had a Chevy or Pontiac engine
since he posted here. Compared to what kinds of mulfunction you can have,
like warped crank, cracked piston rings, broken lifter, broken valve,
cracked spring, not to mention they couse even further damage, I do think
that a set of valve seals is relatively inexpensive. It depends on the
engine how hard is to get to them...

Changing valve stem seals on a OHV engine, with the hads installed, and
in the engine in the vehical can be a royal pain. OHC engines just
slightly less so, as valve lash settings are not a concern.
Most of the time I would rather pull the heads, do the stem seal with
the heads on a work bench. Yes this does cost more, yet any valve or
head problems can be spotted & corrected.
Sometimes Stemseals are blaimed for other issues as damamge, or
'colapsed' rings. As well as pistons with a hole in them. A piston with
a hole in it will suck oil out of the sump, and pump it in to the
exhaust system.

All right, you made your point. But as Andy was saying, his engine is
burning oil so that can have two couses: valve seals need replacement or
piston rings don't seal well. And I said it was more likely the seals. I DO
think that replacing piston rings is way more pain and expensive than valve
seals. Not only you have to pull the heads but also rip apart the block and
the rotating assembly (with the engine out of the vehicle of course).
Compared to that stem seals ARE less complicated/expensive.
