budget USB S/PDIF converter?


long time lurker. thanks in advance for all the amazing info here.

looking for a budget (under $100) solution for usb > s/pdif from my PC laptop. this is a temp solution as i'll be upgrading to a dedicated PC for music that will have digital outs (btw, would love a recommendation for a good sound card with digital out too if anyone has one).

thanks in advance.
