There is only one TRUE soldering iron. If you're
serious
about soldering
and surface mount, you want a Metcal. Don't get the SP-200
series, they're
junk. Used Metcals can be had on eBay. Avoid the RFG-30 bases, those are
antiques (and not in a good way). The MX 500-DS is ideal, as you can use
the 2nd port for either another wand, or the Talon tweezers.
What is the problem with the SP-200?
At a recent local auction I picked-up 8 of these for ?40 intending to resell
on eBay -
A couple of them don't have tips, the others all have high temperature tips.
