As I was taught, do not re-invent the wheel. If someone has done it already, and offers it for free, why shouldn't you use it?
Granted, there is something to be said about writing your own software. But, if it does what you want, go ahead and use it. Save your time for the projects that haven't been done, relase them as open source and keep the programming community moving forward.
