Most of the files are high quality because the vast majority of users are professional musicians and composers.

It lets you download the MIDI file as well as the PDF or PS files of the pieces, which comes handy when you need to read sheet music at affordable prices.
One downside, it has no preview images so there is no way to "visually" locate a piece by its album cover.
FreeMIDI

They have all kinds of MIDI files that you can imagine and you can search alphabetically, or also by genre.

Once again, this is totally free!
It has a really cool feature that lets you browse by top composer, if you are deep into MIDI composing!
One downside is the GUI of the website, it just does not look attractive to the eye and can actually make you feel visually tired.
