Is a Fisher FVH-839 worth getting?

[Ed in Tx]

I think Fisher was one of the most unreliable brands. However we were a Fisher-Sanyo authorized service center, so they kept me real busy! Rent-A-Centers etc. rented/sold tons of them. Don't recall if this model was effected but some of the mid-'80s Fishers would quit working with just one LED lit up on the front panel when the supercap for memory backup would fail. The reset circuit relied on the supercap to work.
