We highly recommend the Second Hand Edition if you don't see yourself using the Royal Compressor a lot. While a few knobs might stop working after the 15-day trial, you'll still get instant analog color, without the in-depth control. If you happen to fall in love with it, you can always upgrade to the paid version. It's important to note that, after the trial, you are still able to use the plugin freely, without the in-depth control.
