You need the 3D+, although the cheaper and heavier 3D can also be made to work. Also there is a 3DF model, which is a little cheaper and heavier than 3D+.
3D+ has a 30mm diameter spindle. So in the future, you also have to look for a frame which bb shell is made for a 30mm spindle(pf30, bb30, bbright).
However, Rotor makes bottom bracket cups that even frames intended for 24mm spindle diameter can also take a 30mm spindle. This leaves the bb cups quite thin, but it's not a major problem.http://www.rotoruk.co.uk/convertors.htmlhttp://www.rotoruk.co.uk/PressFit.html
If you intend to buy all parts new, then P2M price for the crank is quite good. Its 310 euros, whereas the usual online price tends to be around 375. You could source it used to save a little. I've seen a few on Ebay, which have been dismounted from new bikes and they sell cheaper than 375. Watch out that you buy the correct model though, because the sellers tend misuse the "+".
