Get a Weller SP-120 soldering iron. It's 120 watts. About $46. You can
typically find it by Googling.
A ~200W soldering gun from Radio Shack or Home Depot will also work fine.

I'm a cheapskate who uses a soldering gun about as often as I make new
coax lines. (It happens, but I don't spend much time at it.) If you
have a Harbor Freight tool store near you, they have a 180 watt gun you
can usually catch on sale for 6.99. Not as good as a Weller, I'm sure
but so far the solder hasn't noticed.
