Thanks guys for your comments and opinions.
@kgg Good point about the parts. I'm mechanically inclined but I'm don't want to be in a position where I'm spending my time sourcing parts.Having said that, I think these machines are beautiful, and I probably may pick it up down the line if still available.
@Wizcrafts I was hoping you would chime in. I saw a post in another thread that you had a 30-7. See motor below. Thank you for mentioning the revolving foot. I think I'm going to keep an eye on this ad, as it's been available for some time. I can't do both at the moment as I don't have the space for two. It's tempting though.
@MtlBiker Salut! I have an old Singer that struggles with everything except the thinnest of leathers. I made one wallet with it and that is the extent of my experience with sewing machines. I just learned how to make shoes, and my teacher helped with sewing the uppers for the shoes. I did not know about National 2000, I will check them out. You and @kgg make a valid point about the cylinder machine with flatbed attachment. The Post-bed model was a Techsew Demo model,. I'm not sure what conditions the machine was used in, but from the looks of the items he has for sale they look in good condition visually. I am going to take my friend who sews with me when I go to see it and any other machine. Thanks for the offer of assistance, I will PM you after work.
@Northmount "Also may be hard to sew straight lines." Yup, this decided it for me. Thanks!
Thanks again to you all. This is truly a great site and community Cheers!
