Thanks for mentioning PodKicker, ST2. It wasn’t around when I wrote the review (apparently it was first released on June 2011 (really a short while ago), but I’ve reviewed it and added my comments above.

I’ve added PodKicker immediately after the three main competitors – the ones I consider worth using – because even though its new and have some problems, I think it deserves this spot as it looks very useful and I would love to see it being developed more.
