The newer CAD M177's and M179's use the same capsule design as the E350, and sound very similar.
Those can be had quite reasonably, and yes, they sound great on female vox.
And Hookie, unfortunately, there really aren't any plugins that automatically make a voice fuller and lusher. Every voice is different, every situation is different, and what works on one voice won't necessarily work on another, etc. etc. etc.
