That little Gunsmith supply house is about 35 mile Southeast of me. Their catalog is a real toy store to me.
Brownells has them individually upto 1/4 inch.
BROKEN TAP EXTRACTOR - Brownells
Reminds me of christmas catalogs as a kid.

Light heat, penetrating oil, patience, time, patience and more patience usually work.
Don't get heavy handed though. Extractors and the drill bits you would use to get taps OUT are usually hardened - so if you break the extractor (don't laugh - it happens...) you are really hurting.
Another trick (also works on broken bolts) is to use a mig or tig welder and tack a bolt onto the end of the tap (if you can get to the end of it). The bolt welded on gives you something to work with, and the heat of the weld usually helps free up the stuck part. Use a heat absorb putty on the casting to help protect it from weld splatter.

The heat of the drilling and the reverse direction pressure of the drill boring into the bolt SOMETIMES backs it out once you get about 2/3 drilled down into it.
And if it didn't work, you now have a convenient hole to break your bolt extractor off in!

Then about five years ago i bought a VERY expensive set of taps. I haven't broken another one yet, knock on wood, and have also been much more careful, doing the two turns forward one turn back to clear the chips. Sometimes i find it necessary to go two turns in, and then back all the way out to clear the hole and then back in and another two turns and repeat, along with oil, an air gun to blow out chips, its takes so much time to be careful but better than a broken tap.
I think the biggest problem i had early on despite being careful was just cheap taps. I saved up the cost of a couple cheap sets and got a good set and now even the small machine screw sizes are holding up without breakage.
I haven't had any luck with the extractors...
What i have used though is the lefthand twist bits and screw removers that are lefthand thread. If the bit doesn't free it i use that easy out screw extractor and then generally powers them out.
