will do al the avr's and atmegas with their own software.
Why build one if you don't have time, this is a great tool for only $25.
The part number is ATAVRISP-ND.
If you just want to program the classic avr series (not the atmega's)
i found a great avr parallel programmer at kitsrus for $29.00. (Kit 122)
Does not need software except a terminal program. It also programs the fuses.
