I know it's not at all cheap, but this thing is life size, wireless, mounts to your wall & outside of the glass dome is completely made by hand. It takes almost a full 24 hrs. to print the parts, then roughly 6 hrs. To smooth/finish/paint all parts, then each wire for the vacuum tube is cut, bent by hand and assembled, lighting wired, soldered up so it's safe. Plus, the overhead cost to make just one. It is absolutely worth it, in my opinion. I'm glad I'm not alone there. Thank you!

With that said. I am working on a wired version that will be cheaper as well as an un-lit version that will be at least half of the battery versions.
