As you can see on this sub, there are a million ways to go. If money is not an issue and you want something out of the box, you should just google "music production desk" - Output, Studio Desk and AZ Studio Workstations are some of the larger brands with multiple options. If you prefer to stay cheaper our build your own, you can look at getting some table legs from Amazon, countertop from Ikea and adding accessories around it like a keyboard slider, clampable monitor mounts, etc. Stability is important so I would be careful going with some of the cheaper options you may see on Amazon.

As an Amazon seller myself, here are a couple that look good to me. This one by IRONCK is cheap at under 140 USD and the reviews are high at 4.7 with over 3,800 ratings. The price is so cheap that you could add your own accessories with savings - monitor mounts, a larger keyboard tray or even just purchase a 2nd desk to create a L shape. This one by Eureka is 390 USD right now on Amazon and is quite a bit larger and has a "cool" look IMO. I usually like all the products Gator Frameworks does but I don't think their Elite Desks are worth the price tag. If you decide to purchase something on Amazon, I would stay away from anything with less than 100 reviews or a review rating under 4.4ish. Hope this helps a bit!
