Jesus Christ... sometimes I wonder if we live in the same country, king buzzo! You make it sound like you live in outer Mongolia instead of in one of the most densely populated countries in the world. Do you ever go outside at all?
Of course there are pawn shops (pandhuizen) in Holland... there's a goddamn Cash Converters almost opposite of my work place. Google for cash converters or "pandhuis" plus the name of the city you live in. There are also plenty of thrift stores (ever heard of the Kringloopwinkel!?) or yard sales (rommelmarkt, vrijmarkt, beurs, etc, etc...)
Also, a lot of guitar shops sell second hand stuff... there's a second hand section ("occasions") on
www.feedback.nl for instance. And I'm sure your local guitar shop has second hand stuff too. Also check the good old (local) newspaper for advertisements, etc..
And of course the internet... other than
http://www.ebay.nl there's a ridiculous amount of online marketplaces in holland like
www.marktplaats.nl,
http://www.marktplaza.nl,
http://www.2dehands.nl and about a gazillion others...
