Navigating Japanese onsens in Kyoto on a budget during winter

Hey fellow travelers! I've been to Kyoto a couple of times and absolutely love the serene atmosphere. I'm now intrigued by the idea of experiencing a traditional onsen in Kyoto during this winter season. However, I'm on a tight budget this time around and wondering if there are any affordable onsen options in Kyoto that still offer an authentic experience. Any tips on etiquette and affordable onsen recommendations for a cost-conscious traveler like me?
