I have a Fein 18 gauge nibbler that I use to cut body sheet metal and I have a 10 gauge nibbler to cut heavier stuff but it is too clumsy for body work. If you are trying to just make straight cuts on sheet metal, we have several Kett 440s in my shop. I bought the first one retail. Since then I have bought several of them on eBay. They cut 14 gauge like crazy and go on eBay for a around 100. For 14 gauge you need the 440. http://www.kett-tool.com/product_details.php?product_model=KD-440
