VN, the 930 and the 730 each have their pro and cons. As an owner of both, IMHO I would say that the 730 may be a bit better overall but due to the larger numbers of them out there might be considered less collectable.
As in any receiver with a wood case, the 930 does look very good clad in the optional case. I do prefer the simpler look of the 730 myself.
As they are both routinely selling for under $100, it might not be a bad idea to get one of each before the collectors push up the price..
