Having taught soldering to military specs at two different jobs, I gotta say you need good temp control. As with anything, quality is SO important. Of course, like I said it was soldering to mil specs which is nothing like the sometimes lax quality in commercial soldering, but I'm a perfectionist OC freak. I think Weller is your best bet.

Edit: there are some great Wellers, and other brands out there, with temp controls, not like the Weller pictured. You should never use any more heat than you need to make the solder "bridge" and complete the connection within approx 3 seconds.
