You all beat me to this by moments .. I was just eyeballing this for my C1 P60
The Cree XM-L T6 (or U2 if you can find it) is insanely bright for the price. Also it is floody by design. Some will say that a Seoul P7 will be comparable, but I think the XM-L has the edge. I believe Luminus SST-90 will be brighter than the Cree, but the price is nowhere near comparable. An SST-90 can be had in P60 form for around $80, but as this is a budget forum, you won't see much info about that here.
I think you'd be pretty satisfied with the XM-L. Check the reviews for some beamshots with XM-L T6, keep in mind, most XM-L lights will have a larger projector than a P60 dropin:
