I have the UNO and want to mess around with an LCD. I see there are large color options and small mono ones too. What do you recommend?
Go for it.
and want to mess around with an LCD
Just be sure it is a single LCD.
Messing around with a married one gets...messy.
Never mind the pedants...
color:
Color, cheaper, much harder to work with:

Hi,
I like this one: http://arduino-direct.com/sunshop/index.php?l=product_detail&p=92 for quick development because it's a shield and plugs directly on Arduino so you get lots of functionality with no wiring work.
The buttons mean you can implement some interactive / menu system...
DISCLAIMER: I mentioned stuff from my own Shop...
