ChenLinav,
The 205-64 was a great machine before Adler came along with the 205-74 in late 1985. It then made changes and came out with the 205-373, then rebadged it with the 205-370. Finding a 205-64 will not be easy. They are out there but not in large numbers. Going price is $1,500.00-$2.500.00. Parts from Adler are beginning to get scarce. If it was me, I would look at at used 205-370 or new 441 clone. Both are true walking foot machines where as the 205-64 is a bottom, needle feed machine. Yes , the 205-370 or 441 clone will cost more. BUT, parts more readily available as are more types of feet. You might also consider the 205 clone that Weaver Leather sells. Good machine and cheaper than used Adler 205-370 machines which are going for from $3,500 to over $5,000.00 used!!. Buy once, cry once!! Plus the walking foot machines will sew over more difficult items. I have sewn on all of these machines: 205-64, 205-74, 373, 370, Genuine 441 Juki, 441 clones like Cowboy and Artisan, the Weaver 205-370 clone. All sew very well. I own a Durkopp/Adler 205-370 with toys. No comparison between what the 205-370's and 441's vs. the 205-64. Just my 2 cents! Do your homework before you buy.
