Cheap electric height adjustable desk (sit stand desk) from Warehouse Stationary. It's 1.5m wide which is a decent size. Simple design. Controls only allow for up and down with no pre-set heights.
Available in store where stock is available. Call ahead to check if they any, the first store I went too didn't have any left and when they checked the stock of other stores in Auckland it looked like most were gone. I was eventually able to get one from the store in the cbd, i'm unsure if there are any more left.
This desk is usually $499 but was on sale for $449 and then a further discount has been taken off for some promotion. The staff were a bit surprised at how cheap it was so the sale might not be honoured for much longer.
I got it for $349 during boxing day / new year sale. Working perfectly and i am loving it!
