I'am using an Edsyn Soldapullt III PT109 sinds 1975......simply the best......can't live without....!!!!
Wow, I had no idea it was that old.
The original Soldapult is cloned by OK industries and called the DP-100. It is carried by Mouser, which is how I first got a hold of an Edsyn - by design if not by name.
I would caution that these clones are not necessarily that good. I recommended this model to a colleague, and when I noticed they later had purchased a vacuum desoldering station, I asked about the old DP-100. I took a look at it, and the o-ring didn't form a seal, making it completely useless. No wonder.
My DP-100 works great. But I think the Edsyn III is an improvement, for sure. Smaller, quieter, and smoother-cocking, but still as much suction as you would ever need. There's also a small detail in the way it only goes back together one way after cleaning. (Original can be put back together in 2 orientations, 180 degrees apart; the way I use a solder sucker, I cut/melt/form the tip in a specific way so there is only one way I want it to go back together). Another small but important detail is if you want to finely adjust the rotation of the tip, you can spin the tip in the III, and it stays put. The original is fixed.
I don't know what shipping is, but I probably paid around $20.00 for my Soldapult III, several years ago, and I'm pretty stoked with it. I don't see how the tip shouldn't last the rest of my life. Mine is blue with yellow button/endcap. I wonder if the black is an antistatic version.
