I guess it all depends on what your looking for and in what scale.Athearn has decent HO sets.Walthers does also.LifeLike has some sets in Nscale using their better flywheel equipt locos now.Micro-Trains has some in Nscale using ATLAS,KATO,and or LifeLike locos.These should all be available at your local hobbyshop or online.
