The best store software.. with custom product options.

[handeyman]

Hi,

I want to make a store where one can choose custom product options example... color, length.

I want it so I can make different options different prices as well as the image of the product change depending on which option the user chooses.

Anyone know of something like this?

thanks

PS: currently the site is on worpress so a plugin would be best however I am willing to switch to a dedicated store script...
