Mho,,, V4 is the best thing out there as of today. There is nothing (available) even close for under a hundred dollars(ex V3..). The market will probably develop much faster than it did with V3. Especially sinse it's been dead for nearly a year.

The big mesh issues seem to have been fixed. Mesh flow is better. Resolution has increased... Polys have been reduced. Realism is upped a notch. 

Looks like a must have to me.
