I once bought a Raleigh Team Pro that had two well-stuck cranks both with stripped threads. A conventional puller just gouged the alloy but wouldn't budge the crank. If you have access to a press, here's a method that works brilliantly, is non-destructive, and takes just a few minutes.
Back off the adjustable cup about 1/4". Rest the stuck crank against the fixed cup, using spacers as necessary to keep the spindle race from pushing on the adjustable cup. Support the adjustable cup on the bed of the press, using bars etc so the left crank arm hangs free. Press the spindle out of the crank using an appropriate drift.
I have an inexpensive 12T press I bought for about $150 and I'm surprised at how often it comes in handy.
Greg - I see you live not far away. You are welcome to come by if you want to use my press.
