soldering iron

Im about to attempt a repair on an amp but need to purchase a soldering iron. Can anyone point me in the direction of a good iron. I recall reading somewhere in these threads about a haiko, I believe, but I cant recall the details, any suggestions appreciated.
I was in the same boat till two days ago when I bought a 40 watt Weller for $ 16.99 at
Sears Hardware, 7 year warranty.
Hakko is very good quality too.

Next up is this nice Mini Solder Pot from a company called Hexacon for about $ 70.00
Part # MP-945, 946, 947 or 948 depending on your temperature preference (last number denotates temp. in degrees) perfect for my wire stripping & tinning chores.
appreciate the responses, I spoke with the amps tech and he is sending out a resistor that I need to solder to some caps, he mentioned there are a bunch of wires attached to the terminal so what heat range would be appropriate, thanks again
Adding to Jasljs's good post: The wattage has to be appropriate for the job. If there isn't enough, you will get a cold solder joint. Too much and applying to much heat (contacting for too long) and you start melting things other than solder. The lowest wattage irons are only good for component replacement, but won't nearly be enough heat for the speaker binding posts. For general purpose use, a spade tip, like a common screwdriver, is best. A pointy conical tip will drive you crazy with inadequate heat transfer most of the time, unless doing very fine work. And don't move until the solder solidifies. Blowing helps.
I recently posted this question on audiogon and was given the following excellent advice:the Hako 936.excellent machine
reno a 40 watt iron is likely appropriate for that job
