I have a few Metcal STSS-001 Soldering Systems available for
$135 + shipping.

RFG-30 Power Unit + AC power cord
Handpiece with STTC-137 1/16 30° Chisel Tip

These are used, in good working condition. I don't have any Metcal
handpiece stands, but an ordinary 'spring' iron holder can be used.

These are very handy to have. Even though they are older units,
they use the current tips. They heat in seconds and can solder
small or big parts without overheating - the tip automatically
maintains the correct temperature for the job.
