It's shipping from Maine, USA. It's an ok price for a spoke threader. Funny to find it on French ebay!

The damage to watch out for is flat spots in the rollers. Can happen if not enough oil is used and the rollers fail to roll on their pivots. Unfortunately not visible in the auction pics. You'd need to spin the rollers with your hand to see all surfaces in order to verify that they are good.
I bought just the rolling head at one point, and did about 24 spokes with just the head, but then I machined a jig with a crank and all, kind of just for fun and because I had two wheels worth of vintage single-butted tandem spokes to do.
My design for the spoke holder is probably less robust than the Eldi, but it was fun to machine that slot. The brass bolt is custom turned for the job. Over-engineered. I was young, and covid hadn't happened yet to cause me to question my
mortality superfluous machining habits.
