I am new to this forum and thought where better to go for information on two of many machines I have collected through the years. I have a Riccar RZ777 sewing machine and a Good Housekeeper/005123431 which I would like to sell...just downsizing and don't need to carry around with me any longer. Does anyone know the value of these two machines, I would like to sell ASAP. Both machines are in good condition and have hard carrying cases. Thanks Lana
