That one uses 110VAC-powered handpieces. I would be concerned about zapping CMOS with it should something happen to the grounding system.

Look for a SensaTemp or Intelliheat version. Uses 24VDC heaters and won't be as likely to cause problems.

FWIW, I snagged an MBT210, iron /SX70, tips, stands and a bunch of accessories for $120 shipped from CL.
