I need to have 2 separate IIC /TWI/I2C (or whatever you want to call it) networks, the Arduino will be a master on both. I really am looking for an inexpensive IC as I would prefer not to use the I2C software library.

Add an extra I2C bus? (looking for an IC)

Also the LTC4305, that will give you two channels. SMBus compatible as well if that helps.
