I know after reading the posts the last few months and without any support for Lightwave and statements that the Pro version won't work with ver5 and that in the future if there is a plug-in for 3rd party software some features of ver5 still will not be available; I decided to purchase ver4 Pro from Frys at a great price. Went to amazon and purchased a couple of books on 4 again at a great price. Now I think that I definetly made the right decision. Now, CL did offer to sell me ver5 for $99, but why throw that kind of money down the sink. So I bought Mimic 1 with the free upgrade to ver2 and a $10 gift certificate again at a great price.
