The current version is eMU 0204 - approximately $125 at places
like B&H Photo Video.

Unless you need the high sample frequency for wide panadapter service,
any well designed 16 bit/48 KHz USB sound device will provide all the
performance you need at less than 1/4 the price of something like the
eMU 0204.

This is *the most important* determinant of performance.  Internal
noise dramatically reduces the effective dynamic range of the sound
card.
