OK,
Tried their library, just got compile errors in Arduino 1.0.1.

In file included from HelloWorld.cpp:3:
C:\Users\Tom\arduino\arduino-1.0.1\libraries\LiquidCrystal_I2C/LiquidCrystal_I2C.h:81: error: conflicting return type specified for 'virtual void LiquidCrystal_I2C::write(uint8_t)'
C:\Users\Tom\arduino\arduino-1.0.1\hardware\arduino\cores\arduino/Print.h:48: error: overriding 'virtual size_t Print::write(uint8_t)'

Going back to FMs, and try more stuff. Good thing I'm retired, I could have ordered good ones for all the time I've spent.
