What’s the best way to record Skype calls?

I feel very silly for not asking this questions two weeks ago, but what’s the best way to record Skype calls? I’m especially interested in answers from people who have experience making podcasts. From Google, it looks like there are a lot of options out there, and I’d be happy with anything free as long as it works.

It looks like some of the free ones have a 15 or 30 minute time limit, which would be a problem for me, but other free programs don’t have that problem. Are there any other issues I should look out for with free software? From what I understand of how Levelator works, it’s OK if I can’t record separate tracks, because Levelator will handle it all by magic.

Also, it would be nice to have a super-duper simple piece of free editing software to edit out the “um”s and “wait, let me rephrase that”s. I want something simple and easy to use, because beyond using Levelator I don’t plan on doing anything fancy.

I want your comments! (open thread)
