Order price calculator with detailed result needed

Hi all,
I’m looking for my perfect price calculator plugin. As the final user checks the required options/quantities, he has to see not just the sum total of the selected options, but also the list of options he chose with price per each of them.
I saw the demo like this once, but forgot to bookmark it and can’t find it since.
Most calculators I find give you the result of price only. Uiform is the only one so far that resembles what I need, but the demo I lost was more simple and elegant…
