I am so glad to hear that the SE Gold is compatible with RN4081. After winning the started kit on EBay for $40 and finding out from the website that it retails for $150, I was ascared that it would break on my outside my year warranty and I'd have to pay out the nose for things when replacements on other sites are cheaper. Now I know what to look for, I think I'll pick up a few atomizers and batteries... 8^)
