I know either one would probably be a good investment
but what is the
advantage of one over the other?
I can't answer on the former, as I don't have that model. Fairly recently I
purchased a WES51. It's the nicest iron I've ever owned and I'm extremely
happy with it. I believe I paid $70 and some change for it, brand new.
I have also heard many folks touting metcal units. I suspect a used metcal
or new WES51 (hard to afford a new metcal I seem to recall) would serve
quite well. In this particular case, unlike most other efforts of mine
computing related, I would prefer a brand new unit.

Jay West
