I do ergonomics for a living and also work at home.
Go to amazon and find a well rated model that fits your desk.
Either get a desktop model or the full table/desk you posted.
Key is to ensure it can handle what you put on it.
I love the new powered ones.
After adding two monitors, laptop and docking station they get very difficult to move up and down.
Ensure you alternate siting and standing.
Use a cushioned mat and beware of trip hazards. http://www.memic.com/SAFETYACADEMY/PopularSafetyTopics/Ergonomics/tabid/228/Default.aspx
