I was just going to add that you can check out pluginboutique.com for some free stuff and some of it - not all of it - is pretty awesome. A favorite of mine is Ample Guitar lite and Ample Bass lite. Source: over 3 years ago
Massive synth - can get you some really heavy basslines as well. Its on sale at pluginboutique.com by itself or as part of the NI Komplete Select package... Source: over 3 years ago
I've been pretty happy with pluginboutique.com. They usually have a good freebie every month that comes with whatever you buy from them. Last time, I got the Cherry Audio CA2600 synth for free when I bought a cheap $10 plugin. Source: almost 4 years ago
