I just got a hcigar copper penny mod clone today for $40 and it's really nice. It's a 23mm mod and i have a hcigar dark horse clone on it and it hits really hard with a dual coil .31 ohm build on it. Major vapor and great flavor. I see your in ohio too, i don't know what city but kings of vapor is where I got it for $40 and it's well worth it.
The threads are super smooth, it has a nice weight to it, no burrs on it anywhere that I've seen.
