Have ordered a lot of stuff over the years. Never had any problems with them. They even search in the warehouses for parts for me. Frank was a great guy working with.
Mike at AMS Obsolete is local to me. He has never not produced just priced high for my liking. Has it been enough time since ordered? Does not sound like his style.
I have visited him and walked his yard and warehouse. A little disorganized IMO but he has always been prompt, just wanting premium prices. I will say he had lots of small items I could not locate anywhere else. Took some time to locate but they were hid in the giant warehouse.
