What is wrong with a normal pic? As long as you get the flash ones you should be able to reprogram as many times as you want... The compiler from microchip uses C (the student version is free)...

Hey, thanks for all the help guys. It's my day off, and after a few hours I've got some elaborite LED flashin' going on. Soon to voltmeters and displays!!!
If anyone reads this later, I highly recommend this tutorial: You guys have probably seen it already.
I thought I was going to kill myself there for a while, I didn't have any of the exact chips in any tutorials and they had different port names and stuff. Now it looks like it was worth it.

O___O Bjoern
The company I work for uses PICs in many of our products. (and I'm the po' sucka' who writes all the firmware.) We've never managed to destroy one on purpose either, though about 1 in every 200 just mysteriously never works. We don't know why, but at the moment it's not cost-effective to spend time figuring it out. I once dremel'd all the legs off a 44-pin surface mount PIC and replaced it with a fresh one, only to discover the damn board still didn't work :(
We recently had some products returned where the customer had plugged them into 12V instead of the 5V they're designed for. I expected the PICs to be fried, but the flash memory was just blanked, and after reprogramming they worked fine again.
I must admit that I've been seriously impressed by the Philips ARM7 based chips since Bjoern wrote about them here. I'd probably choose them over the AVRs or 18-core PICs if I wanted a more powerful micro that could run code written in C happily. But the 16-core PICs programmed in assembler are great for getting cheap'n'nasty jobs done.
