Since I was curious, and the Jiecang link the sibling posted was for minimum 100 piece orders, I had a look.

Aliexpress is where you want to go for single quantity orders. Here's just one of a few that I found there: http://www.aliexpress.com/item/Electrical-Sit-and-Stand-Heig...

EDIT: Holy wow, I totally missed the shipping on that thing! Anyway, I'm sure there's more affordable options there, for those in the market.

Here's a good start: http://www.alibaba.com/trade/search?fsb=y&IndexArea=product_...

Jiecang and Linak are popular suppliers to a number of US companies who use the bases, add their own desktops, and distribute to US customers for $500-$1000

Thanks a lot for the link, time for me to do some research on this since I'm very tempted to do this at home.

Here's a pretty inexpensive option in this realm if you don't want to take the time: http://www.ergoprise.com/s2s-height-adjustable-standing-desk...

I don't have this particular brand but a feature I appreciate on my adjustable desk is the ability to save height presets.
