on the link avove there are severial different options for the products.

i know i can do this with attributes but with over 500 prodycts my list of atributes is massive and it takes longer to find the right bits than it took god to make the earth lol

is thre a way which i can do or something simular??

You could make the overall item a subcategory and the individual options products. The product listing page could be manipulated to look like the example (more or less... I wouldn't want to copy that pink shopping cart button! ; )

The example site is built with Microsoft Visual Studio and a ton of javascript.

doing that would effect the whole site and i have other items which aint like this.

the site there is a competative site to my own and they are making mega money and im not even getting sales :(
