I like it as well. you do need a machine with sufficient memory though.
you can download the trial version and try it out as long as you like, save is disabled.
Ivo's also very helpful and provides prompt support.
the auto stretch doesn't always work for me, but there is the manual stretch.
and yes, fixing the star shapes is pretty cool.
also does a great job with vignetting, gradients, colour gradients, noise.
there are a few videos on youtube
