Someone told me that CRT monitors have lead in them (About 8 lbs). Would they be worth trying to salvage? How hard would it be to get to the lead?

Forget it... The lead is chemically part of the glass, a Lead Silicate in combination with other silicates, not as the metal.
It takes a whole heck of a lot of know how, very hot temperatures, furnaces, and chemical reactions to make this happen.

+1 what Tom said. The purpose is to capture the X-Rays that are naturally part of the operation of the CRT. This goes for computer monitors and CRT television sets, B&W and color.

Ditto to what has been said. Not worth it.

....and yet lead/glass of any form is banned in many landfills. So explain to me how easy lead leaches out of lead crystal glass?

Another environmental wacko fairy tale?

It is not how easy it leaches into the soil, it is how the word is spelled. If they knew anything about chemistry or physics a lot of the things that are banned would not be and quite a few that are allowed would not be. If they knew how to do something they would have real jobs.

Yep. Another fairy tale... Glass does decompose, but it is a very slow process that takes literally eons.
Glass ties up metals, and vitreous materials are fairly stable.
One of the methods of disposing of radioactive waste is to combine them with silica and turn them into glass. That wouldn't be done if the glass form is unstable.
