Re: Buying midi loops. Reason vs N...
What style/instrumentation of MIDI loops are you looking for? RnB, DnB, Pop, Drums, orchestral, etc?
Did you know that the Green apple loops that are bundles with Logic contain MIDI regions? You can use these with any software instrument of your choice...

Have you checked out the Reason tutorials here to get a sense of what the instruments are capable of?
p.s. here are a couple of places that serve up MIDI files:
