Looking for a nice Model M 1391401 series, US ANSI.
Please let me know what you have.

I'm also would like to get 1390136 model.

According to current DT quotation: $69–300 (Depending on version, year of production etc)
$217 (1992)[2] and considering the following diagram: Are you willing to shell out 250$? What do you think is the fair price?

Is it that expensive?
Why?

It was just a reference. Anyway as you see the range is wide.

And

As usual the middle way is better @99

No idea why it costs that much..

I think 100-130€ is a reasonable price, depends on condition of the board.

One problem I have with the three examples from dcopellino -- no offense intended -- you're looking at currently selling ads on ebay. You should be looking at sold ads to determine an average price. Breaking out my Latin skills and trying to convert that into Italian, the highest price for a sold Model M was 220 Euros (90 degree adapter needed) and the lowest was 91 Euros (PS/2). I left out a couple that were even less expensive because they fell outside the date range OP specified.

@hellothere, I agree, even though the graphic chart already shows the current objective prices trend. The point is how much is it worth for you who want it now.

Another retro calculation could be that of observing what hasn't been bought on eBay looking at closed auctions with no bets. For instance, the attached pic would show that on eBay accessed from an Italian ip today. And expanding the search with a more common keyword....I found that. The last listing is mine. no greed at all!
The highest and successful bid on a model m ended at 91€, not shown here, though.

Looks like hard to find ANSI version...

ANSI in Europe is not going to be easy. Your best bet is to get one shipped from the US....

With this finding, I think to have seen all.
