[vcf-midatlantic] Monitor repair class test subjects

I'm getting my material ready for the monitor repair class I'm doing on Friday, and Jason I know is bringing a monitor with some faults as an example. Looking around, I seem to have fixed most of the broken things i had laying around that were obvious. I'll keep looking, but, has anyone got a monitor that has a fault that they think would make a good demonstration? I *think* Will had one he said he could bring that has messed up vertical, I can ask him to bring that along if he has it handy. But if anyone else has anything convenient, let me know. Preferably monitors that either are self contained terminals, or take composite video, to make getting some video on the screen simpler with limited amounts of hardware. Thanks! -Ian
