[Closed] Cheap internal dropper

I currently have a KS eten and am very happy with it, however [s]when[/s] if I get a new bike it will have internal routing so I'd like to get a new dropper to go with it (also because of the different seat tube diameter).
Trouble is I can't spend too much, below 200 if possible.

KS seem to be the best option, are there any others I haven't heard of?

Or should I just shim my current dropper and stick with that?

Also - anyone know the difference between the KS cruxi and eteni? I can see the head is different but are they the same internally?

Edit: 125mm would be nice too but the cheapo ones all seem to be 100mm...
