I bought an inscr r11 Cloudburst wand about 2 months back for 5k.
It's probably just people having fun with being overpriced; a quick look at wiki shows it to be tied to both NF and EotN, so it's impossible for it's value to be anything close to an oldschool/dualmod.
That being said, wait for more opinions, as well as I'd be interesting in buying your Cloudburst wand (not for 100e... lol) when/if you're willing to part with it. PM me if yah do ;D
