Just received my ZD985, $179.99 delivered from eBay seller memotronics_llc (
http://www.memotronics.com). Five day shipping from Houston, Texas, double boxed, very good.
Desoldered an UPS board similar to the one Dave did and it worked just as Dave showed. No draaaama!
Differences between mine and what I saw on Dave's video:
1) All wires to the output plug are shrink-tubed, remembers Dave had a loose wire and it looked like no shrink tubing.
2) My solder collecting tube is clear (glass), Dave's was dark blue(?).
3) The spring in mine is an open coil, doesn't do much. Dave's tight coil looks like a better design.
4) Color: Blue gun and case with white trim.
Copy of spare parts list attached.
Cheers, Mark
