Since I don't have a TIG torch (yet... coming soon) I use that technique 
with my MIG welder,  with very good results.   I've never had any luck 
with so called "easy-outs".   They always seem to snap off, and then 
you're twice as screwed.

If you have to drill them out, you might want to try a carbide spotting 
drill.   They are super hard, and don't wander around like a twist 
drill.  They don't cut like a twist drill, but you can use them to at 
least start the hole, which is the hardest part of drilling out a stud. 
    Due to their design they are much less likely to snap off too.

Enco and MSC generally have import variety bits that are only a few 
bucks a piece.   Money well spent if it saves you from snapping a drill 
bit off inside a stud.

Of course pretty good MIG welders can be had for cheap now (sub $400) 
and I don't think anyone should be without one.   They are sooo handy to 
have.
