Your library is suitable if you want slow updates close to the ground before landing. Sometimes that is all we need for a Quadcopter.I have been flying for months. I recommend beginning with a KK board. It has gyros, it's simple, and it just works the first time. KKv2.0 has accelerometers too, to keep it level. It's hard enough to fly even with this, impossible without it the first time.
The next step is a pressure sensor to keep it steady at a particular altitude for example 10m above ground.
Then a compass to keep it pointed north, now it's easy to control the x,y position manually with only 1 stick on transmitter!
I've found a 2D compass works if you have a KK2.0 board first.If you're still having fun add GPS. Hobbyking has a frame and 4 motors for $30. Let me know if you have any question!

I considered the KK due to the extreme low cost. But, will probably go for the Crius AIO Pro because checks all the boxes and is only $63 for a ATmega2560, 10DOF (including the MPU6050), and GPS can be added for only $25. The KK2.0 is interesting, but I want more control, not less. Also, I decided a deal-breaker was any ATmega328p-based flight controller due to the lower bit PWM control. The ATmega32u4 with its (6) 11-bit PWM's was considered (in the NanoWii and the Pro Micro). But, the price is higher than the Crius AIO Pro once you add a magnetometer or flight controller to the Pro Micro. I really like the NanoWii. But, the price is already very close to the Crius AIO Pro and adding a magnetometer puts it over, before a altimeter is even considered. The Crius AIO Pro is really hard to beat in price, and it's not missing anything either.
ESC's and motors are my issues now. First I was considering the Turnigy Plush, but then I read about the SimonK firmware and found the RCTimer SimonK 30A ESC's. But, I'm worried about the lack of an external resonator in it. So, I'm considering a HobbyKing F-30A and flashing the SimonK firmware myself. But, the F-30A isn't in stock, and typically hasn't been for years now ;-(
Then there's the motor issue. Finding a quality motor that's not too expensive has been a challenge. I read recommendations, only to read later that the model has changed or there's new quality problems. Looking for something in the 2836/kv850 range that can drive a 1147 prop (I'm going to run Lipo 3S). The Turnigy 2217/860kv seems like a good motor, and I can get 4 for only $58.
I'd like to get everything from one place, but it's starting to look like I'm going to be making a few different orders. Suggestions?
