Well, I own Gold, Vocal Rider, and the CLA Bundle which I use frequently. I don’t pay too much attention to the sales now because I have more than enough plugins now. But the Wave Plugins are very good. It took me a little while to sort out the licensing, But once I got it, all was well.
One thing about the Waves Update Plan. Unless they’ve changed it, you get the 1st two years of upgrades free, which is more than (ahem…) most anyone else does.
