I dragged my feet buying the model 35P so long now that a friend has a model 43 with all the goodies minus the laptop needed for sale for $450. So my question is, seeing how I've never used it before, should I go for it, or just get the 35P? What would you do? My buddy has the laptop for now. Does anyone know what these things will really tell you as far as BC, drop charts, groups etc?
