Panasonic PV-V4520 4-Head Hi-Fi VCR
The noise is a serious defect.
I have to agree with the other comments here.  What good is a VCR if the sound it makes whenever a tape is in motion (playing, rewinding, or forwarding) interferes with the sound coming from your TV?  Plug in this VCR, and you'll suddenly feel like you're living under humming phone wires.
