SX's cost $4-5 USD in smallish quantities.

Also, months ago, I invented a routine for doing hi-speed
multi-channel PWM via lookup table stored in RAM. For 64 bits
bits, with 20mhz PIC, you could go about 1Mhz/64 = 16Khz, but
you get to 8 channels. With SX, it goes 10x faster. You do have
to slow down of course to reload table values.
