You don't have to spend a lot of money to get a decent gaming mouse. Corsair's M55 RGB Pro mouse covers all the basics, and most importantly, it's only $23.99 right now on Newegg. That's a discount of $7 from the usual price of around $30.
The M55 RGB Pro has an ambidextrous design, so it works equally well in left and right-handed use. All the basic features you would expect from a gaming mouse are here, including a button for switching between DPI modes, a few programmable buttons (which can be mapped to macros using Corsair's desktop software), and a durable lightweight construction.
In our review of the M55 RGB Pro, we wrote: "This mouse will serve you well, but it’s Omron switches are very slightly resistant—a colleague described it as 'spongey'. In addition, I found the scroll wheel harder to reach with my fingertip grip than it should have been. But that’s it; for the most part, the M55 is comfortable and responsive for everything from twitch-shooters like Apex Legends to action-adventure games."
