You can buy this stuff for less than $50:

For poor hobbyist like me it's a bit to expensive. You could ask designer of the USBasp why bother and reinvent the wheel. Many people (including me) are using this programmer. Description of this programmer says that it supports 5V devices only but in compability list i found 27C256-12.7V and other 12.7V chips. Which one should i believe?

I would rather use ATmega32U4 with real hardware USB peripheral.

For now I'm using RS232. When I get this first prototype running I'll try with fullspeed USB.

Actually I need a cheap programmer for Game Boy cartridges.

Sooner or later I'll buy of the shelf programmer but for now I'm broke.
