I am selling my Rosewill RK-9000. I've had it for about a month, so it's in great condition with the original box.
Just recently, it's started registering keys twice (T E S and O, if it matters). It's completely random, nearly impossible to reproduce, and rarely happens. But, it happens enough to annoy me to no end, so I'm selling it. Apparently this is normal for Rosewills, or mech keyboards in general? I don't know, but I had to mention it. (For the record, it happened once while typing this post.)
I'd return it to Newegg, where I purchased it from, but they want to knock off $40 because I no longer have the "free" headset that was included. The below price is assuming this is a normal occurrence. If it's not, feel free to yell at me and I'll just return it.
Asking $75 and shipping to the lower 48. Shipping would be about $10 for Parcel Post, $15 for Priority.
