I have had good luck with utsource.net (buying only from seller "utsource"). Yes it's the Chinese lottery but they have a website, a mobile app and a us customer service phone#. They also have the decency to tell you they are selling pulls:
https://www.utsource.net/itm/p/210129.htmlWhenever I have had an issue, they have taken care of it. Shipping speed is decent also.
They are like Amazon now, allow third parties to sell. I only buy from seller "utsource".
The scammers are clueing in and registering stores named "genuine utsource" and 'real utsource" which are still 3rd parties.
Otherwise for obsolete parts you're paying $$$ for surplus or taking your chances with Chinese fakes/remarks.
