In 1994 the state-of-the-art SoundBlaster would have been the AWE32 and it was $399. You must be misremembering :)
Sound cards did not drop to anywhere near $20 until the very late 90's or early 00's and those $20 cards were bottom barrel stuff that would have been less advanced in many ways than the GUS Max even then.
Now I remember why I was never able to save any money in my late teens...
Too bad it died after a couple of years, seems to be a design flaw
I was profoundly disappointed to have to deal with this sort of nonsense when we "upgraded" from our Amiga 500.
That card was so good for demoscene stuff..
I was also proud that it was Canadian-made (it sat alongside my Matrox video card)
The only thing I remember I was amazed and sad at the same time when I heard the SB2. Halve the price twice the sound.
And ofcourse Dr. Sbaitso..
Cut out a part of the PC cage so it could fit. Added memory from an old video card to it and it worked great.
But things were going so fast that maybe one/two years later the Soundblaster 2 came on the market. Maybe it was $200 and producing much better sound.
Edit: changed the prices as others point out they are wrong.
