Well..DH convinced me to go ahead on the repair. I have 3 large and 5 small tops of mine to quilt and 4 twin size for a customer that is willing to wait until my machine comes home.
Our thinking is that the repair will pay for its' self in about 6 months. Talked to Handi Quilter headquarters and they said that the new board should last many years...i think maybe more yrs that I have. I am 77, so I don't think I want a bigger debt. After I get it back and will work at it..I will post the results of situation. it will take 4-6 weeks to get her back. Thanks for the suggestions.
