Fixing eBay?

eBay is unsafe when one has to buy expensive products, especially from foreign countries. This is breaking eBay's business model. What if we could use a trusted third party entity that would check that the product matches the description and that the money is there to allow the transaction ? This would have a cost, but for expensive products it would be worth to pay a commission shared by both ends for such a guarantee. Requesting to use such a third party relay could also be a proof of honesty.

I guess it could be possible to build such a relay network by using small shops (i.e. press) for a small side income.
