This is the one I purchased from mpja
https://www.mpja.com/prodinfo.asp?number=15140+TL
34.95, temperature controlled and comes with an extra heating element. Tips are cheap, heats up relativly quickly. I'm VERY happy with this purchase and it's one of the reasons I recommend MPJA.
I use a 15 dollar 30 watt radio shack special (I hate that thing) for desoldering, and I abuse it heavily. The MPJA unit only gets used for 'real' work where good joints are a must. The heat up and cool down times feel like an instant if you've ever used a radio shack cheapie, even their more expesnsive temperature controlled units don't even come close.
