Quantities & prices per option?

I'm developing a site selling products which are available in different colours at different prices and where customers might want to buy a combination of different options. I can do this by setting them up as different products or as one product with different colour options but the options are either a check box or select box. is there any way of having a Qty box with each options so a customer can order for example 3 blue and 2 red on the same page?

I guess it needs to display something like this:
----------------------------------------------------
PRODUCT A

Qty: __ Blue £2.50
Qty: __ Red £2.75

[Add to Cart]
-----------------------------------------------------

Does anyone know if that's possible?

Thanks.

Perhaps this is what you want?

Fantastic - That looks great.

Quick update - paid for the extension and it works great :-)

Enjoy!
