Good inexpensive sensors and gyroscopes...

I am attempting to build the inverted pendulum robot and was wondering what sensors, gyroscopes and accelerometers would be good for my mini project? I don't want to spend crazy amounts of money and was hoping someone could give me a few good examples and where I might be able to obtain them?

List your sensor requirements

I use the MPU 6050 gyro/ accel sensor in some of my projects and it should be fine. You might find it for $4 on ebay / chinese website. It uses I2C communication.

I don't need it . You're the one that needs to find it.

Search ebay for 9 dof or 10 dof. I got one 10 dof with accelerometer, gyro, magneto, pressure sensors and a temperature sensor on the pressure sensor. All is for $13.
