The other thing I've found about Weller is
that they sell spare parts
I am really fortunate here in SoCal, several very serious dealers of weller
etc. are at the local hamfests. One very nice guy, I think his last name is
Fue, started buying and selling soldering stuff after he retired, and now
he is one of the major sellers on the west coast.
I've known Harold Fue for about 30 years or so as he came to Santa Barbara
at the same time as we did. Among other things, he is also a ham. Sure makes
it nice to have his stock of parts here!
