I want to sincerely thank you for your help when I was just getting set up because you were very helpful to me on the phone a few times when I needed advice. You helped me a lot,  and your AV-40 is an excellent machine well made and well designed.  Your videos also are top notch for a beginner to learn from. Best wishes to you in the years to come.
