Trying to repair my ECU.

Instead of starting a new thread...Ill thread my question into this one as I think its appropriate and Im repairing my mother boards.

Im a novice solderererer. I like the adjustable heat irons, but do not know what else to look for. I have a couple of those Weller non adjusting irons and Im going to blame the tool for my crappy work. Ha! Any guru info? Someone said to get the soldererer sucker in the kit. They all seem pretty cheap online. Tips? Tricks?

Thanks FABO! Is this a hi-jack if I place this question here?
