With the exception of higher end consoles, the prices have tanked on these at least here in Montreal. I see many in restorable condition for $50-$100. Don’t overpay as for the most part,gen Xers and onward have no use for old radios or old anything for that matter. The buyers for these are ageing out IMHO. As with collecting anything, (cars,Radios, antiques) only the truly desirable stuff retains its value. Do your due diligence.
