I just started rock climbing recently. I don't have any gear of my own and the first thing I wanted to get was a rope. There are various ropes of different prices. What should I look for when buying a climbing rope? I understand that I'm not supposed to get used rope since it can be hard to tell what it's been through (factor-2 falls, exposure to harmful elements, etc). I'm asking what features are important for a good climbing rope and what features are just marketing or only applicable to extreme climbing cases.
I'm starting out doing some single pitch bolted routes. No trad climbing yet since I don't have any gear of my own yet and it will take a while for me to piece together what I need, so it's one piece at a time. Don't worry, I'm not going to get the rope and think I can climb without the harness, belay device, shoes, etc. I just wanted some perspective because there are tons of different ropes with different features.
Edit: By the way, I won't be doing any ice climbing or climbing in alpine terrain. I've never even seen the snow in person!
