I'm also always on the lookout for mics. I've been looking at a Sontronics STC-10. It's bizarrely cheap, almost ridiculous not to get it... Like 150 dollars or so. It can't be that bad since they're selling it :S
Also I like the Oktava mk012 and I'm thinking of buying a pair.. Not too expensive either.
I'd also like to know what contact mic to get, I don't wanna build one... I've seen the Barcus Berry on the web being used but I can't get it in Sweden as it seems...
