Your favorite (cheap) 8 bit DAC?

[Theo]

Not that familliar with PIC, but for cheap DAC functions I like to do PWM.
If you have a spare counter things are real easy.
On a AVR you can get about 10 bit resolution with out much problem.
(some AVR counters have this function buildin, maybe PIC counters do too)

Pro's: 
1)takes only one cpu pin, 
2)low component count, 
3)cheapo solution.

Con's: 
1)limited resolution, 
2)[often] eats a counter, 
3)disign of the proper output voltage range is more work than with a DAC.

Regards Theo.
