I'm working on a search engine for second hand musical instruments.
It is still in beta which means there are some tiny bugs and some finetuning has to be done.
But it works!
At the moment there are more than 50.000 ads in the database.
Because I'm Dutch, most of the search results are from dutch online marketplaces but more and more non-dutch sites will be added in the (near) future.
Go give it a swing and tell me what you think about it!
