I assume because you inquired about a serviceable unit you must have priced one of these lovable fuzzy "detector" on line? OUCH. I am going to be really careful about making sure mine stays in working condition. That's unreal, the price they want for that. What happened?
There has been times while cleaning bugs that I have slammed across that unit but now I know to be extra careful.
The site on ebay that has the Skymaster that is being parted out, wonder if they have one?
