I have a 1947 version (KMC); it's been a while since I typed with it, but my memory tells me the action was quite similar to other manufacturers' standards from that era. I don't think the popularity and long production of the 17 would have occurred if contemporary professional typists found it had an inherently heavy action. 

How common are Remington standards in your area? I know they were also manufactured in Europe, but for some reason I'm under the impression they're more difficult to find.

I have the same experience over the years with Remington standards starting with my typing classes with them in the 1960s.  A friend and recently retired typewriter repairman started his career with Remington in the 1940s and owned a sales/service business and Royal dealership close by in Eugene Oregon.  I once asked why there were not more Remingtons, it seemed there was much more Royals and Smith Corona. His reply was people felt the key action on Remington was heavier and preferred the others. Frankly I didn't think any difference was that much.
