Several! I recommend starting out with something not too overly expensive (you'll crash), easy to repair (you'll crash) and sturdy (you'll crash). Oh, did I mention you will crash?

TX: Turnigy 9XR or FrSky Taranis (more expensive, but a good investment since you probably won't crash this one...)

Frame: any 330 size frame will do. This one for instance: https://www.banggood.com/DJI-F330-4-Axis-RC-Quadcopter-Frame...

Motors: 2212, ca 1000kv will make it pretty sporty

ESC: 30A

This combo set is only 19 bucks: https://www.banggood.com/XXD-2212-MotorZTW-AL30A-Brushless-E...

Flight controller: Naze32 or CCD3. Doesn't really matter. This one is fine (it's in my latest quad) and is only 11 bucks: https://www.banggood.com/DALRC-NAZE32-REV6-MPU6050-32-bit-6-...

You'll need extra props, wire and nuts and bolts. 400 dollars is totally achievable!
