I use a rod warmer. But not electric one, but a rack to hold my rods and preheat them in the back of the flame. It really speeds things up.
I have used a Czech cast iron rod warmer. You can see the set up here. You point your torch downwards towards the metal holder. I do not think these are available in the US.
I now also use an Italian portacana. Same principle, different set up. I think some versions of these are available in the US.
