Waves NLS Non-Linear Summer is on sale for $99 ($249). I already own this and I'm very happy with this console emulation and what it does with my sound. Try it as a demo!
These are 96 uniquely modeled channels plus master channels from The SSL 4000G belonging to Mark ‘Spike’ Stent, The EMI TG12345 Mk 4 desk owned by Mike Hedges and The Neve 5116 console custom-made for Yoad Nevo. This is summing emulation, not replacement, so you're still using the main Live audio paths and NLS adds unique character to each channel.
I'm using it on my electronic drums and they really turned into something else, more cohesive and heavy.
Make sure you gain stage and send in about -18dBFS RMS into it. Then drive it as hard as you like.
Obviously working OTB with real analog desks is often the best, but I can't afford to work like that, nor have I the room for it.
