AVR-Chat

Hello, I am new to the list here.  I am considering moving up from a 
Basic-x system.  It is nice, but more limited than I would like.

I have seen the atmel 128 (or even better for me, the 1281.  I need 
more than 24 i/o lines and I would like at least 3 external 
interrupts so I do not have to arbitrate them over a single 
interrupt (some are higher priority).

I _do_ like the simplicity of the BaxicX -24 boards.  Just supply 
power and it is ready to program.  NO other stuff (memory/cyrstals, 
etc).

Does anyone know of a source of a complete, ready-to program and 
interface board for the mega 120 or 1281?  Small size is a plus. A 
DIP package is a plus as well.  Low cost is really important.  US-
based sources would be nice to avoid international shipping and poor 
dollar exchange rates.

I have seen some nice ones, but many of the I/O pins are taken up by 
other headers (dallas, etc).  I think I would rather keep as many 
I/O pins free as reasonably possible.

Thanks in advance!

Tony
