It has a weird interface, but basically, say you were looking for a Peavey 5150, you would put "5150" in the "search" space, and then under "model" you'd chose "Peavey" and then hit go, and it lists you deals from craigslist, ebay and Kijiji. Or if you were searching for a Profire 2626, you would put "profire 2626" in the search bar and select "M-audio" under model. So really they have it the wrong way around...in "search" you put the model and under model you select the company/brand/manufacturer/etc.
