You can build an AVR910-compatible ISP programmer pretty simply using 
either an AT90S1200 or AT90S2313 (see the URL below).  Of course, you 
need a programmer of some type to program the AVR used in the 
programmer.

I built the 2313-based device and it serves quite well.

The AVR910 nomenclature derives from the Atmel application note 
describing the ISP procedure, available here:
