I'm trying to physically downsize my electronics kit, so I'm looking for a soldering iron I can keep in the toolbox more easily than my Weller WTCPT. It's not really for true "portable" use, so I don't want to deal with a butane iron. I've been looking at the Weller W60P and W60P3. First, what's the difference between the two? And secondly, are there other irons in this class -- decent quality and temperature regulation but without a base station -- that I should be considering? Thanks!
