Questions About Light Intensity/Meters. Help!

Can someone please give me some feedback on these questions? I'm in the process of building my first room and any help would be really appreciated.
1) What is the most popular way to measure light intensity? Is it LUX or FC?
2) What is a good light intensity for seedlings? Clones? Vegging plants?
3) Where's a good place to get a light meter? I've seen ones from $30 all the way to $500. All I need it for is to determine the light intensity at any given point in the room. I don't need any special features like digital memory. Is all I need a light meter that measures in just one of the units of measurement (LUX or FC)?
Thanks a lot for any time,
~ D
