Used prices - transceivers

[VK2XSO]

What would be cool is a live site where it had the buy and sell offer prices.
The buyers can make an offer even something considered silly and it would be expected that somebody selling might list higher.
Ebay actually has something similar already but it's a one on one process, not a public one.

If an item sold then it could be looked up in a history of the site, almost like a stock or commodities market.

Want to sell an IC-2A, you can look up what the last couple sold for.
Downwards trend you might decide to sell sooner or buy later.
