[LAU] is Behringer reliable as USB to S/PDIF adapter?

I find myself in need of a USB to S/PDIF adapter. Does anyone have experience with one of the low cost Behringer interfaces, UCA202 or UCA222? I have an audio interface, so I am not very interested in the analog performance of the adapter, I just need reliable S/PDIF operation. The manual for both of those devices indicates 16-bit converters, but does not make mention of whether the S/PDIF data path is also limited to 16 bits, or whether they will pass 24-bit data. Has anyone had opportunity to check that? And lastly, any alternatives I should check? The Behringer is easy to get and only about US$30, which is the primary reason I was considering one of those modules. Input and output would be nice, but output is all I really need currently. -- Chris Caudle
