Is it possible to have the main price dynamically change depending on attributes

[Prophotoboy]

Hi there, firstly, Id like to say "hello" to everyone.

I have a question, I’m new to zen cart, and I'm in the final stages of getting my shop live, in which I'm selling scenic photographic prints. I've worked out how to use the attributes, (thanks to the posts in here )but would like to know if there is a way (or a mod I can get) that will dynamically change the main price -displayed by the item- as the choice of attributes are added e.g. size, colour of mount, choice of frame, before the item is put in the cart?
Also, do you think I would be better off having the different sizes of prints as separate products, rather than having them as attributes? This is the way I’ve done it at present, but not sure it is the best way.
Any advice would be very much appreciated. Thanks. Mark

Look at Chrome's dynamic price updater.
