This is the same price as an IBM model m though
Not with shipping, though... IBM M's have more collector's value.
Here are the recent eBay sales of IBM 1391401s, for example. Of course people sometimes list them with undervalued BIN prices, so you can't really go by that. By my reckoning, 1391401s in decent, unrestored shape are currently going for around $80 shipped, on average.
