I drag solder and clean up with wick for small stuff like the LM3409. My main beef with the CAT chip is that they're a low side regulator and when they fail they tend to fail closed, so if you have a bunch of them in the same circuit and one fries, it'll usually take out most or all of the others. At least they don't tend to kill LEDs since most of the time they're run with a really small voltage drop which is fairly safe. I've never had heat related issues with the CATs and at any rate their thermal shutdown is effective enough to prevent themselves from burning out due to thermal stress IME.
