Now I have cleaned, adjusted, and lubed this board. It is very nice and I will not be selling it (at least not until I find an upgrade specimen!).
Coming from my trusty Model F, anything else will inevitably feel "plasticy" and lack crispness, so that is a given.
First, I really like the looks of this board. The beige keys are pretty nice doubleshots, if rather ordinary, but the darker keys are a really nice color, much darker, warmer, and richer than the M/F standards I see every day.
The footprint is small, good for those people who have small desks, and the board is light in weight (no metal plate to be seen, it has plastic with one of those cardboard / foil layers instead).
It is pretty quiet now that I lubed it, and my only real complaint is that the keys are a good deal heavier than I would like.
Ripometer says 65-75 grams, with a few almost reaching 80 grams (holding 14 nickels + 1 quarter + 1 cent). It seems like the more heavily-used keys are stiffer, and the less-used ones are lighter, in general.
The wear pattern of these keys is very surprising. Whoever owned this keyboard originally must have typed a lot of text almost exclusively. The letters are worn, and the most-used third of them are quite shiny. There is a spot to the right of the center of the spacebar that is heavily worn and totally shiny. The right shift is showing just the tiniest bit of wear, but "Enter" looks almost new, as do "Backspace" and "Delete"! The numpad looks like it has never even been touched, like the top numbers and Function keys, same with the modifiers. Even the arrow keys show no wear! Who types like that?
Conclusion:
If you want to try white Alps, and don't want to spring for an Omnikey, this would be a nice board to have.
