Going off of Gregvacs's post...
I got thinking about the smaller companies consolidating like Greg mentioned. After thinking about it, the only ones I can see staying around are Kirby and Aerus (and correct me if I am wrong, but does Aerus still own TriStar?) The others (Filter Queen, Rainbow, etc), although I really like their products, and have owned them in the past, unless if some drastic shift in the market happens, I don't see much of a market for them. The reason I see Kirby staying around is because Scott and Fetzer is owned by Berkshire Hathaway. To me, what would be a good arrangement is if Berkshire bought Aerus, and either left them as a standalone subsidiary, or put them under Scott and Fetzer.
