I used the D300 with Microfiber and the Foam pads, it can be used with either. I think the main difference is that the MF is faster, but you can still get to the same place with foam. I personally preferred the foam, because I had so much trouble with the thin MF pad on the curves.

I would definitely look into trying a smaller backing plate before buying an extra polisher. On the Griot's the 3" plate with a 3.5" worked really well. I also preferred a flared pad to give myself a little extra buffer when using the smaller setup with a large polisher.
