Are you looking for a relatively cheap computer desk that is height-adjustable? This AUKEY Dual Motor Height-Adjustable Electric Standing Desk might be the thing you are looking for. It's not very big (48" x 24") so your computer will need to be on the floor, but it's ability to go up and down (height range: 0.7m to 1.2m / 2.3ft to 3.94ft) is a desirable feature for some people. Right now it's about $100 USD off the normal price, bringing it down to an affordable $140 USD.
