So true. Althought it's pointless to add to the recent Freaks "AVR vs PIC" thread, this is one of the most significant reasons why I prefer the AVR line. They are inexpensive, the programmers can be very inexpensive, and the C toolchain is easily within reach of the hobbyist.

I have $40.00 in PICs and a nice programmer sitting usb programmer for them I have never used. I just can't find the value in jumping back to ASM to make use of them.

I have a Microchip 1000 or 2000 ICE thingy that cost about $2000 and was used for one project.

Given a choice I much prefer the ECROS ICE Cube, avr-gcc, and of course an AVR. With AVR prices the way they have been I have an easy argument for AVR. My use of AVR isn't big by some measures but about 2500 ATmega64L's per year the past 4 years are running my code.

Strangely the JTAGICE mkII didn't work on the above hardware where the ICE Cube did. I put a small 50 mA or maybe 100 mA linear regulator on the 3.3V supply and the mkII drew more power off the target than the regulator would provide. Didn't know that for a long time because the ICE Cube worked so well.
