I have been going back and forth on ordering the Motorola video monitor. I know from the reviews it's quite a bit better (and apparently lasts longer) than most any other monitor on the market. The 3.5" screen is significantly more expensive over the 2.8" screen. Those of you who have ordered/owned one, is the addtl screen size worth the extra $$? Or does the 2.8" do the trick? My frugile side and the side of me that wants to get something that will truly benefit us is currently at war!

Thanks in advance! : )
