It's not hard to build a good quality (not top level, but good) DAC for less than $50.
JEDAC (http://users.abo.fi/jskata/JEDAC/ http://users.abo.fi/jskata/JEDAC/) is a good example of a cheap DAC that is reasonable quality. I don't think that TI does their free sample program any more, but at one point as a student, it was possible to build it for a few bucks.
I guess if you're paying full price for your ICs and you're factoring in labour, it's not any cheaper than buying one, but if you don't value your time and you're handy with a soldering iron, it's definitely worth it.
