From what I have seen, the demand or want for Roth (and Ruth) seems to be less than that of the starter avatars in SL. Even Opensim users don't want it. They prefer the shamelessly and blatantly copybotted commercial mesh bodies from SL.
My suggestion would be Kalhene Erika. Great customer service and support by the creator & team. It's an affordable, versatile and gorgeous body with so many options out of the box that still doesn't get enough recognition from clothing creators.
