I believe the $29 HF rotary mentioned above is made by Zhejiang Wuyi Surpass Tools Manufacture Co., Ltd, which is located in Wuyi City, Zhejiang Province of China.
Here's the link to the HF unit with the LCD that's made by YAT Tool...

Another rotary that has intrigued me is this Proline unit being sold by Tool Price and other companies. I don't know how heavy it is, but it does have electronic speed control, soft start, a nice RPM range (0 to 3000), both a 'D' and straight handle, ball & roller bearings, etc. It's sold here for $69 and at well over $100 at other places. Even though Tool Price and other companies say this tool is made by Pro Line Products, I believe it's really made by Supowertools in Hong Kong. Here's the link...

And if you look closely at this specific model of the Coleman Powermate PMB7284, you may see a resemblance to the Proline with very minor differences
