Source for Uno chips with bootloader?

I seemed to have lost my boot loader on one Uno & Fried the analog on a second one. Where can I get fresh processor chips with the boot loaders installed?

Thanks!

Adafruit used to ship Atmega328's with a bootloader on them.

Sparkfun.

If the rest of your 328 works you could burn your own bootloader.

Digikey, Jameco Mouser have the blank chips. If you are going to abuse them you might as well learn how to load the bare ones and save yourself a few pennies (so you can afford to blow more chips...)

Totally agree, I never get tired of seeing that first blink test sketch run on a newly burned Arduino.

Get one of these as well, then you can easily program you standalone Arduinos in circuit -

I always include a six pin header on my standalone circuits so that I can use the serial monitor, upload updated sketches and have the option of powering them through USB also.

I have a sketch here that programs bootloaders (the bootloader is inside the sketch):

Just hook up 6 wires, run the sketch, and you have a bootloader-enabled chip.

Wow! Thanks for the replies!

I went to Adafruit, found the chips and some other neat goodies so I ordered them.

I'll have to see if I can try flashing them myself, I know where there is a stash of blank chips.
