You can choose between the Aothia Leather Desk Pad or the MROCO Ergonomic Mouse Pad as two examples of great budget pads. The first is slightly more expensive but often comes with huge discounts ($12.59 at 26% off), while the latter comes with a regular price of $7.99. Your decision should depend on whether you prefer leather (Aothia) or cloth-based (MROCO) surfaces.
