Just a note to say that I just ordered a purple/yellow Mathmos Astro with an extra blue/red globe. I live in the U.S., so it was ridiculously expensive--but as I defend my masters this week, I think I deserve it :).
I've tried the china lamps again and again, thinking I could get one that worked eventually--but I can't. I love lava lamps so I decided to drop the change and get a good one... hopefully I am not disappointed.
Hope you didn't find the post worthless--thanks for sharing in my excitement!
Hopefully the cloudiness won't be an issue... If it does happen I'll feel screwed, because shipping the things back would be so cost prohibitive. I thought of the cloudiness issue after I ordered, but I'm hopeful. It may help that I live in Michigan, and not Arizona. We'll see.
