AVR-Chat

Thanks John,
There is an offer now, either:
STK500 + Dragon $50
STK500 + JTAGICE2 $150
I don't have either, and I'd like to be able to debug in circuit...
Is the Dragon also an ICE?

I don't know if/when I'll want to use a >32k chip... but how confident are 
you that the Dragon will eventually (and when) work with larger chips?  
Couldn't there be some limitation? Memory? Something?

I'd like to save $100, but ideally I'd rather not be sorry later :-)
Maybe I want too much :-D, but $50 doesn't need much justification when I'm 
only playing with it (hobby), while $150 needs 3 times more :-D

The Dragon is for devices with 32K or less flash for debugging.
It can also do HVPP like the STK500 as it has a socket which can
be jumpered for any DIP package. Cost ~US$50.00

It should eventually be able to program all chips.

JTAGICE2 can do all chips for debugging but no socket for HVPP.
The price for this has been around ~US$300.00 (has dropped lately)

So if you only need chips with max 32K then the Dragon is a good choice.
