hi all

i started looking for a free programmer to build by myself on the
net, and got lost in 10 minutes: isp, bootloader, could someone
please explain me these?
Isp seems a cool feature, but do i have to "sacrify" pins?
Then, what is a bootloader?
I need to find a free programmer that works wit IC-Prog (or whatever)
and that i can build by myself, with the plus of isp.

What does your experience suggest?

Thanks a lot!

Faisal
