We just looked at and bought a tiller. IMHO, the upper lines in Troybilt and BCS are really nice tillers. We bought the BCS 722, which is equivilant of the Troybilt Horse.
Having used older Troybilt Horses, and looking now at the latest model, as well as the BCS line, I don't think they have changed or cheapened. They were solidly built and looked just as solid as the 20 year old Horse I had used.
The entry line of tillers, I could not tell you about. But, the bigger heavier units are nice.
