Recommendations for photo stitching software for Mac

Title says it all…

I am looking for a cheap and cheerful app to stitch together photos into panoramas.

I haven’t paid registration so all I’ve toyed with is the demo, but DoubleTake looks like a good one.

Not bad. I fiddled around with DoubleTake for a few minutes and did this:

Rio de Janeiro

That’s five photos stitched together, with the shareware watermark.

Any other tools? Favorites?

Photo-stitch software came with my Canon digital camera, did you not get any with yours?

Here’s a thread on dpreviews on the topic.
