What BluRay Drive for ATV2

[fuseman13]

I have a bunch of DVD's I've ripped, and would like to do the same for my BluRays.
What Drives have you used? What speed do you suggest? Manufacture? Model?

I have a iMac 21.5" 2011 (about a month old) and that is what I plan on using for the encoding.

No one at all?

I'd say the faster the better...there are some 12x BD rippers out there...
