I am sorry not to have thanked you earlier for posting such informative thoughts. The many things to consider when purchasing a machine seem endless. The Designer 1 continues to capture my eye. The buttonhole wheel may take a bit of practice. “Pushing the correct buttons” as an alternate method to making buttonholes may be the way to go and is certainly an avenue to explore. The fact that the Designer 1 does have upgrades available with no additional charges is certainly an advantage.
I wonder what purchases other then the machine may be required? Does Designer 1 come with an adequate supply of feet? What type of out of pocket expenses can be expected in the maintenance area? Should a used Designer 1 be purchased does the warrantee from the original owner transfer? The machine appears to be a giant sewing computer. Computer experience must be a plus in the learning curve. Again, thank you for your continued answers to the many questions.
