Good question! As with most of the stuff, everyone's got his/her own idea of value. To me, this card is worth it because of the onboard midi synth - although the 2Mb version is probably better for those with more discerning ears. This card also holds some nostalgic value to me since it was the card that came in the very first machine I bought for myself back in 1995 - a Gateway 2000 P5-75 beast of a tower - and more importantly, it's the first time I heard wavetable synthesis. After playing some DOOM and Descent and hearing what this card could do to general midi files, I've never looked back! I do remember the SB Blaster Emulation of this card being rather crappy though, so I always disabled the PCM/WAV portion of the card and threw in a true soundblaster card for DOS games. Generally though, in Windows the card did OK using the native ports. From a monetary standpoint, the real money seems to be associated with the Ensoniq SoundScape Elite - which essentially the 2Mb ROM variant with a DSP effects-processing (reverb) daughterboard.
