Can you explain why the need for the desk to be electric type? There are much cheaper standing desk that's manually adjustable, like this MultiTable one: http://www.amazon.com/gp/product/B006269Y4E

They've been around for several years and always been cheap for less than 600$, I've seen 300-500$ that works as well.

I have this table for more than 2 years now and it has never failed for me. It's also very quiet, no motor running the desk.
