I think I remember seeing MP05 once in a store for $500.
Now, compared to the continued fees needed to legally own a Megatron Transformer, that might seem like good value, but you have to remember that if you get caught with one without the legal approval you'll be in a lot of trouble.
Personally I'm going to try to own it legally.
Hopefully Griffin will be able to find new information of how to be exempted from the fees in Victoria and other states. Or at least the an exemption or reduced amount for the renewal fees every 3 years.
I've personally emailed the licensing regulation regarding the fees numerous times, but their responses so far have been very generic. The most helpful they've been was in clarifying that there are no additional storage requirements other the the imitation firearms section I quoted earlier
