Best $100 - $200 USB Coverter

Ouch, my Windows XP dedicated music computer just died. Bad motherboard… Bad karma. Just picked up a refurbished computer and need to connect it to my DAC via a 15’ SPDIF cable. Unfortunately, I’m on a strict budget of about $100 - $200. It seems, I can either go with a USB cable to an SPDIF out external sound card (option 1) or use a USB to SPDIF converter. My old computer used the M-Audio Revolution 7.1 sound card with great success, but the card won‘t fit in the new computer. Would love your opinions on the “best sound” options within this tight budget.

1. M-Audio Audiophile USB External Sound Card (I believe comparable to my last system)
