Absolutely...
SWS extensions something to get one's head around after a few deep breaths and a walk around the block. Extends function more than most of us can dream, and guess that this is what it's ultimately all about. Dream and be given the avenue to do it.
In the same vein, the Jesusonic plugs unique to Reaper. Has raised hell fire and brimstone condemnation for the name. Was introduced however with a reverent premise. If Jesus were here as a modern day rock musician, what plugins would he want to have available to properly shred away. What would have been Christ's standard.
The JS plugs are incredible,incredible text files allowing the end point user ability to reprogram the effects to one's own new creation. You got a tweek to a reverb, flange, comp, echo, then dive in and publish your own. Always used the stock JS's as a starting point to compensate for my ignorant inability to start programming from scratch.
Kite's advice about getting the $60 personal license can be taken to the bank and several more times around the block.
