I picked up a KS Eten around 8 months ago because it was cheap $120 and I didn't know how much I'd like it. It is heavy, has a slow return, I don't care for the stock lever, but the post works and I love having a dropper. I'd like to get a better one but they all seem to have their reliability issues and I really don't want to spend $250+ on a POS. The only one that seems to be super reliable is the Gravity Dropper which just uses a spring but it is fugly(don't care) and $300(do care).
