I have stumbled across a Shibaden video tape recorder/monitor model SV800UL and am considering buying it to play with. I guess I would like to know what an example of this model is worth with excellent cosmetics but untested functions. Also, what type of tape can I use on it? I have done some research, although very little seems to be available on the internet, and it appears as though Shibaden didn't use a compatible system with anyone else's. Is this correct? Again, what's a fair price to pay and where would I get some tape? Anything else I should look out for on this model?

Thanks in advance.
