Electronics questions

I don't have much experience scrapping electronics besides the occasional TV, and I was thinking about getting into it more. Most scrappers in my area don't take electronics so I think I could get quite a few things. My questions are:

How much can I expect to get from TVs, PC monitors, PC towers, cell phones, printers/ scanners, DVD players, etc.?

Are there any other common electronic devices that I'm missing in the list?



I'm sure I'll come up with more questions, but that's all I can think of for now. Thanks
