If you have more time than money, here's a possible option:

  - Buy IDA Pro using a credit card
  - Find bug or two, submit to bug bounty [1]
  - Pay back credit using bug bounty money

If life were so simple, everyone would be doing it don't you think?

My friend's grandfather was an economist. When he was a little boy he saw a $20 bill on the sidewalk on a walk with with his grandfather. He pointed to it and said "Grandpa look someone dropped a twenty dollar bill! We will be rich!" His grandfather dismissed his enthusiasm and explained that if there was free money on the ground somebody would have picked it up by now.

There's an evaluation version of IDA that's an older version and doesn't include 64-bit disassembly (just x86 and ARM IIRC), but it's free.

And is not available for my operating system.

What's your operating system? I usually run it under Wine on Linux without a problem.

OK, sure, but I still don't see how this is relevant to whether IDA is better than Panopticon.
