I would just wait for Renn Maxx to go on sale since you seem to like the Renn Series.
It goes on sale quite often...and you'll spend only a few dollars more to get all the Renn
plugins. They are also included in the bundles as well (Silver, Gold, etc...) which go on
sale all the time and are great value...
And just like that, bam! On sale TODAY ONLY (5/2), you can get Renn Maxx for $118.99 when you buy from
Audio Deluxe (price shown in cart). Not a bad deal. (I checked Plugin Discounts and Waves Universe just now, but they didn't have the sale price up yet.)
If you buy the Maxx bundle, you're free to sell the individual plugin licenses you already had at whatever price you can get. The Waves license transfer process is quick and easy, as long as your WUP is current (which should be the case if you bought within the past year), and Waves, unlike a lot of other companies, charges no transfer fees.
The Gold bundle is also a great deal when it's on sale -- it's been below $200, but it may be a while before it is again. Curiously, not all the Renn plugs are included in Gold. Missing are the Channel, DeEsser, RenBass, and RenVox. They are nice to have, but Gold is chock-full of other useful tools. If they interest you, it may be better to wait for a deal on that bundle instead.
Cheers,
