okay. bring up that page. on the left-hand side, starting at the top read down until you see "view catalogue by product type". click there. it should bring up a huge list. that's where you'll find everything they offer, even what's not on sale. click on the thing that interests you. you'll get the manufacturers that make that item. choose the one you want and the right item comes up. put it into your cart OR click on 'prices' on the upper right to get more info and a close-up.
EDITED TO ADD: three years ago i bought the curvemaster at a show. i paid $25 for it in 2007 dollars. they have at now for under $19 as the not-on-sale price.
