Whats the best router to get for cheap?

My router broken today so I’m trying to figure out what type of router to buy. I don’t want a really expensive one cause i just need it for the next 3 months. But I’m not sure what router would be the best to go with. I mostly use my internet for gaming. I’m not even sure which routers will work with my modem, so I’m just gonna try to find one and try it out if it doesn’t work I can always return it. Any suggestions?
