I paid $3800 for mine three years ago this month. Overall, it's a much heavier-duty unit than the 1000-series. The transmission is fully-servicable (fluid changes and filter changes). Best of all, power to the transmission is shaft-drive rather than belt-drive.
Unlike the 1000-series, it's rated for and designed to pull ground-engaging implements. IOW, it's not just a lawn mower, but it can do a few low-end tractor jobs as long as you're not expecting full tractor capability. With wheel chains and some weights it will do a very good job pushing a PTO-powered snowblower if you're in snow territory.
