My advice is to research other controllers or just save up for something nice like Ableton Push - a fantastic controller with all the bells and whistles that are not found with the MPK25.

The MPK25 is an excellent MIDI controller

After I modified the drum pad sensitivity, this controller is awesome.

This little controller is perfect for travel studios

The MPK25 controller is incredible

Very good controller for home studio.

It's much better built and has a more intuitive layout: http://www.amazon.com/M-Audio-Axiom-Pro-49-HyperControl/dp/B001RH9P2OIf you're not a keyboard player by trade and are using Ableton Live, I highly recommend the Ableton Push controller - it was a game changer for me (guitarist)
