well if your going the chris tomlin/hillsong route, they both use korgs string sounds.
matt glider from chris tomlin uses a triton rack unit through a s90 as the controller
and Ben and Autumn (hillsong, hillsong live and hillsong united) use everythign from the triton le, to the m3 for a lot of their string sounds (also some of mainstages string sounds)
i know you didnt wanna go to computer route so that rules out mainstage but you can check this out i think it may be jsut what your looking for
