I will not for a second state that I can do without reverb in my music. I'll just get that out of the way right up-front.

Pulsar II comes with three reverbs - the MasterVerb Classic, Pro and the E-Flector? I think they're the ones anyway. Are these all I'll need?
I want reverb for individual tracks - eg vocals, piano etc. and for mastering on the final mixdown.
There are some very expensive and impressive looking reverbs available on this platform and for the native solution as well, but should I be shelling out or should I be very impressed with what I already have.
I'm very interested in what people have to say about this, because I will purchase a 'must have' but would rather not pay out big money on something I really don't need.
Thanking you all in advance for your feedback.
