hahah - Yeah, I wouldn't even attempt a repair if things were corroded. I would just use the packing that comes as a strand you wrap on if I didnt see the correct packing within a minute. I wouldn't even re-grind the seat, IMO if the seat is toast on such a valve then replace the valve.
Actually, first thing I would do is just see if tightening the packing nut doesn't fix the leak!
The repair would cost under a dollar. I know, time is money. I have the packing material in my plumbing box along with some washers and such. I don't have any spare valves at the moment. If if all I needed was a few turns of packing material I would be done before my truck even warmed up. Provided, as you say, the old valve isn't all corroded and junk.
