This is the one I have...they sell on ebay with shipping including. I think I got mine for $99..but that was a couple years ago

I never really had an issue with the spring pump tubes...they worked fine once you get used to them. Then I borrowed a Hakko..wow was that nice.

I ended up buying the one linked below and have been using it for a couple of years. The nice thing about it is it comes with a bunch of accessories. I think three tips...cleaning stuff...a ton of extra filter pads...even a replacement spring. The Hakko ends up being 2.5x the price plus a bunch of different tips at $30ish each

The spring doesn't get clogged if you use the grease provided. Actually..that's wrong..it does get clogged but a tap on the work bench cleans it right out. It MUCH lighter than the Hakko..which his nice if your running a bunch of monitor chassis.

The one thing I do NOT like about the 474 is the power on indicator. It only lights up when the heating element is active. So if the tip is to the proper temp...the light shuts off. It can be tricky to make sure you shut it off...because it sometimes looks like its off...when It's on
