I have an older Sony Betamax SL-2401 in pristine, paramount shape in my closet. It hasn't been used since 1984 but I'm sure it's still in great working condition. I've checked Ebay and I see some players going for as high as $70 US and I've even see some auctions with Buy-It-Now list prices of $200.00! Can anyone offer a suggested value for this unit, assuming it's in great functioning condition, and accounting for collector value, etc. Thanks!
