I've been trying to get the cost of my electronics projects down. The most significant savings I've found so far is to use processors with a single UART (atmega169 which goes for $3.81) and to avoid LCDs with a serial interface. This meant I had to get used to using the Hitachi parallel interface for writing to the LCD. It wasn't a big a deal and now I'm saving $7 on each processor and $12 on each LCD. I found this site the most concise and functional for connecting a Hitachi LCD to a raw AVR part.
