Amazon has it for $9.99 digital, and $11.48 disc. If you're the type that winds up with lost or damaged discs, I would consider the digital.

It should still run on W10 if you use XP compat mode. You may however have to run the Windows Troubleshoot Compatibility wizard before installing.
Made for XP games aren't "ported" to W10 though, or Vista, 7, or 8. Windows uses Compatibility Mode for backwards compatibility. It's just that a lot of people don't know how to use it, or especially how to install via it when necessary.
Note that in W10, I don't necessarily recommend trusting it's Use Recommended Settings option, where it often chooses Vista. Instead select the Troubleshoot option, and when it asks what OS it worked in previously, choose XP.
You will see the Troubleshoot Compatibility option once you right click the game's install exe. In W10 it should be about the 5th option from the top of the list shown when right clicking. This list is called the Context Menu of the Explorer shell.
