For the OP, here is the link for the custom ROMs allowed to be linked to on this site.
Custom Roms - Droid Forum - Verizon Droid & the Motorola Droid Forum
Google "Blackdroidmod" for the links for Ultimate droid.
PS: I would read up on Rom Manager and the common issues associated with it, and decide if you want to use that, or SPRecovery. Ive been rooted for over 6 months and never had an issue with SPRecovery. Never had to re-flash it, never had an issue. It might take a couple more steps to install a ROM, but it is FREE, and thats always a good thing in my book.
