Zoom makes good units now. I like one that takes a WAV file as well as MP3 but it's not critical.

I just run the output of my MP3 player into my PA amp. The connections of course depend on what you have. That amp has two channels, one for my MP3 player and one for my mic, and so I just 'mix' with that.
