FlexiSpot EF1
If you want your best standing desk to be motorized but don't want to spend a lot of money, consider the FlexiSpot EF1 (formerly known as the FlexiSpot EN1). It has a silent motor lift and a keypad with three height presets that may be modified. There's also a customizable alarm that will notify you when it's time to switch from sitting to standing (or vice versa), which is quite handy.
The frame is made of double-steel tubing and is quite robust, however it may have a few wobbles when extended to its maximum limits. This FlexiSpot standing desk is amazingly inexpensive when compared to competing motorized goods, offering some fantastic features at this low price point, and the business backs the desk with a five-year warranty (and the motor gets a slightly shorter three-year guarantee).
