As mentioned, parts are parts. Like a garden variety 1/4" x 20 nut is generic, so a garden variety 1K resistor is generic.
If you're starting out, reclaiming parts from equipment would give you some experience desoldering and learning how much heat is too much. If you destroy something it's no big loss. You can reverse the process and solder the recovered devices to a header, while refining your soldering technique a little more, which can then be inserted into a breadboard to give you instant, reusable switches for prototyping your projects.
