HDR Darkroom--Good deal @ $20?

Available today and today only at this price at the mac app store, but there's more. No wait, no more, that's all. Is it worth it for a dabble in HDR?

Here is a link with reviews from people who have actually used the software: http://www.flickr.com …iscuss/72157622​884385602/

I've never used the software, but I thought this might be useful. I think the going consensus is that software like photomatix is a bit better but HDR darkroom isn't bad..?

From this consensus, I can't see any reason why it would be a bad thing to get if you would like to dabble in HDR.

I've "dabbled" in HDR, but am not a big fan. That being said, I wish I had only spent $20 on hdr software...
