hiFace make a USB to S/PDIF which sells for about £100.

Can anyone recommend an alternative product offering
better quality for a similar price, or a similar quality
at a lower price ?

It all depends.

What sample rates and word sizes do you want to handle?

If 16/44 or 16/48 is all you want, then commodity units selling for $30-50
will do the job.

What format SP/DIF?

If optical will suffice, then even the Behringer UCA 202 @ $30 will do the
job.

Any possible sound quality issues will be up to the DAC that you plug this
into.
