I like Time-Serts. I strongly recommend getting the seat reconditioner tool as well. It ensures that you have a flat surface for the plug to seal on.
Edit: I also like to keep one of these around in case of emergency.

I would not use it long term, but sometimes you need something to get you home or through the week.
Edit2: Given how easy it looks like it is to pull the N62 lower pan, you may want to consider replacing it if you can find a good used one.
