It sounds like this machine will do everything you need it to do... if you have the money and can afford to do it without giving up something that is a necessity I say go for it. Two years ago my 1977 Pfaff broke and could not be fixed. I found a Baby Lock Serenade that had all of the features my Pfaff had, it was expensive when my husband and I set down and talked about it he said if it lasted 1/2 as long as the Pfaff it would be worth every penny we paid for it. I have it setting out and use it everyday.
It really is your decision and only YOU can make it.
