I'm sorry but I think we get ripped off here. I've read the entire thread and there has been many heated discussions about this on Melband (Aussie site, Melbourne) about this very issue.
Yes, there a pro's and cons to both arguments and I understand that distributers have $1000's tied up in stock. So do shops in the US. I also understand that they have to make sure that regulations and approvals are met and that it does cost a few hundred dollars (I think from memory $300-500) for testing and approval of electrical equipment for that revision product (one off cost for that revision only). Subsequently if there's another electrical revision on that product, approval needs to be gained again. OK, understood.
However, how does it explain that if I buy an amp from a shop in the US, I can still get it so much cheaper? Said shop still pays wages, insurance, shipping (to shop), rates, utility costs etc., In other words, I still pay for all their overheads and running costs. In Australia, it's the same, right? Granted, the actual costs as a direct comparison may be cheaper in the US but I'm still paying for it, regardless.
Now consider this... when the distributor over here orders, it's direct from the manufacturer, or at the most, from another distributor. They won't be shop prices that you and I pay. Also, shipping costs are not what you and I pay. They get a discount and usually by a huge difference. Do you think they'll pay $300~500 for only one amp? I think not.
I may have said it simplisticly but to me I feel that we do get ripped off. A case in point, I boughtt an entire One Spot power supply combo pack for $50AU shipped to my door. Here, just the power supply (yes, only the power supply) is $50 or so, let alone $6~8 or so for each cable/adapter and Multi-Plug 8 Cable for $33 and so on. Getting ripped? You bet.
It's time Aussie shops give us a fair deal, not a ripoff deal. Let's face it, we get ripped off on everything, not just musical gear.
