For something basic, Motorola makes an 8-bit D/A in a single 14-pin DIP.
Raio Shack sells it for $2.50 to $5 depending on sales, etc.  That's cheap!
Needs a couple resistors to make it work, but takes TTL inputs directly.
If you want deglitching, slew-rate correction, etc, you'll have to roll
your own.  Oh yes, the Motorola part ("DAC-8") is current-mode output
(one resistor makes that voltage) and has some multiplying capability.
Ideal for home computer music experiments.
	Yes, PAIA is a great source of cost-effective hardware for music
synthesis.  They have a "well-tempered DAC" whose output is exponentially
related to the digital input--used to drive linear VCOs for music.  mike k
