Bingos are boat anchors out in California. Unless they are fully playable, you can't even get $50 for them at Auction (Believe me, we have tried!!!!). They have to be fully shopped and looking pretty darn nice to get any interest at all out here.
I believe you were right in the first place. About $200 for the Playball and leave the bingos behind. Don't know about Hi Fi but I own a Big Time and it doesn't have much going for it. At least B/T has the magic lines. It doesn't appear Hi Fi has any special features?
