So I'm looking to use a PIC for three channel PWM lighting control on a project. The PIC16F685, 690 would seem to fit the bill. 4 PWM channels should make things easy. The PIC16F737, 747, 767 and 777 would all work, too, but are more expensive. I can't seem to find much on a compatible programmer for any of these. I can find ones that say they're compatible with other 16F6xx chips, like the El Cheapo. Is it safe to assume the reason such PICs are not listed is because it is a list of tested and confirmed PICs, and one of these might work just fine?
