I am running a rooted 2.1 droid official using the 2.1 sbf.
I've installed some mods like the mms mod, music mod, launcher mod and such.
Personally, I feel that roms are unnecessary, and that most of the roms are overkill anyways. If I want a mod, I google on how to add it and do so.
This way, if I install a mod and my phone becomes buggy, I know where to begin.
