I call a farce on that price, last time I tried to buy from the germany, the strip alone in my quote worth 30+$ just for the strip and rotary plastic ....

Ruhlatec something, unless I've been completely screwing by browsing, but 5$ for that ammount of LPI is really cheap.

Alternatively, I've taken habit of scraping encoder printers and their motors. I end up accumulating encoder.
Just beware though, finding the pinout is a pain in the butt.
