I remember hearing a that there's a problem with ODE and Blitz. There was an implementation done before userlibs were added, but it started breaking down after Blitz got upgraded (that's just what I remember - could be wrong ;) ).
The nice thing that separates 3Impact from other physics 'things' is the mesh convertor. You model your convex-hulls and mass distribution stuff etc. in the conventional way and don't have to worry so much about esoteric numbers / trying to build collision objects in code (AAAARGH).
I haven't bought it yet, but like I said for £50 it would be rude not to ;)
