[sdiy] WHICH PIC/UCONTROLLER should I buy today

[cheater cheater]

Hi Dan,
I have not read the whole topic but Terry on this list works for
Freescale and can get you some nice stuff if you ask nicely :) Also he
has mentioned to me recently a nice DSP-enhanced uC that is real cheap
and could fit the bill for you. The dev env was real real inexpensive
as well from what I remember.

Cheers,
D.

>> Some of them have an I2S output, so you can easily connect a 16 or 24 bit audio dac if you want. Some of these chips have HUGE on-chip flash: 512 KB. Great for storing wave forms for example. Prices are between 2-10 euros. The problem really is that there are so many to choose from:
