I'm guessing once you start using CKMs it becomes addictive.....
I'd had an icord machine for ages, then started with a preloved 48 pin Sentro, quickly bought a preloved 40 pin machine. My latest to add to the collection is a cute 22 pin machine bought new off ebay very cheaply for £11 (approx $15).
I figured for the price it wasn't going to be great but it's surprised me. It rattles and isn't the smoothest movement BUT it is working brilliantly with the thicker aran yarns with napp that just don't work on the other 2 machines 😊. It doesn't have any suction feet so I've improvised and use the rug stopper stuff under it on the glass tabletop.
It's pretty cute looking too 😁 my first make after practicing was a mug cosy.
