Is nidalee good? Other good 3150 junglers

Yes. Her early clearing takes some getting used to but she's very good.

Can they be cheaper than 3150?

Practice makes perfect on Nidalee. You're either really good at her or you're anywhere from decent to fail at playing her. You have to dedicate time into playing that champ really well. Be good at landing spears.

As for 3150 junglers- is fun to play and you can be really creative while playing him. is a staple among high elo picks, offers excellent gank potential and you can really tilt people in low elo's by doing well on this champ.

1350- are really good for low-elo pubstomping but you need to be fully aware about how much damage you can dish out vs. how much you can take. gets extremely tanky, and theoretically his clears aren't the best but he offers pretty great gank advantage early-mid game. One big drawback about Sion is that if you reach late game he becomes a walking meat shield and can be rather easy to avoid taking damage from. if you're decent at timing, you can do well on Rammus. excellent for surprise buttsex, but you need to be creative when playing her, just like Shaco.

Hope this helps

Very good but difficult to play.

Shyvana and Gragas are also good 3150 junglers and I think they're easier to learn.
