Not sure if that the correct spot to post such thing,

I recently lost my WiFi survey tools on a europe trip, and I m looking to buy everything from scratch - but the prices are just crazy.
looking for used items now. Does anyone know a website to buy WiFi tools (ebay and amazon are no-go) . Or is there any retired WiFi Genius who wants to sell his WiFi package.

any guidance or ideas are very welcome
thanks a lot.
