Need to Set up Advanced Search

I’ve been trying a lot to built up the advanced search widget for my product site. Let me explain this with an example: A user wants to refine search results as Samsung Galaxy Tablet in the price range of $400-$500 and so to perform this, he should get first drop down list as Brands where he can select samsung, then he gets the second drop down list as product where he selects Tablet and last he gets a drop down as price range with option 0-100,101-200 etc. I am using the shopperpress theme with amazon products so need to refine those thousands of results. Is their a plugin to do that as I don’t know about using custom fields or taxonomies.
