Sorry, Metcal is now marketed under the name of OKI. I have a Metcal MX500 soldering station. It is rather unique, in that the tip that you use determines the temperature at which the station operates. Tips are available in 500, 600, 700, and 800 degree increments. The power supply for it is about 10" tall, 5" wide and 4" deep. It's a monster of a soldering station. It heats up in about 30 seconds and will hold its temperature, even on the largest of ground planes. With a 5mm 700* chisel tip, it will heat up a 5.5mm connector (that is clamped into a steel jaw vice acting as a heatsink) and the 12 wire that I am soldering into the connector in about 4 or 5 seconds, depending on the ambient temp.

I know that many might disagree, but in my opinion, it's the best soldering station that you can get for basic electronics soldering. The one that I have retailed for about $500, but I got mine on ebay for $200. Additional tips can be had for about $12 on ebay. It's a kick butt setup.

I've soldered everything from very fine electronics (0603 sized smt stuff) to making repairs on 1/2" diameter copper rod with silver solder with this thing. OK, I'll stop raving. I just love my soldering station.
