I own one and I must say, for the price you are getting a really great quality display piece.
There are a number of innacuracies which the Indy prop experts would be better suited to comment on, as discussed in prior threads, however I myself being a picky collector was willing to accept the faults of the design in favor of the overall quality, displayability and the generous price tag.
There are a number of unlicensed replicas of the Idol that are more acceptable to the die-hard Indy prop collector, the most noteable would be the 'Gobler' Idol.
RPF members Jedifyfe and Risu would be the first two guys that pop into my head that I feel would be best to direct you in the right direction off-hand.
