Show lowest price of products in same category

[Menace]

Hello!

I'm using VM 2.0.8e with Joomla! 2.5.4

I would like to show the lowest price of a product in a certain categoy on categories overview.

For example if I have the category "Sofas" I would like to show the price of the cheapest sofa in that category to be able to create something like "Sofas as low as $299"
It's not the big problem to echo a price on categories view. My problem is how to always show the lowest price automatically even if new products are added.
