Any using one of these?- http://www.littlemachineshop.com/products/product_view.php?ProductID=1877 Is it worth it?

Hi Paul,
Just browsing some old posts and came accross this, I have one and yes it's great for small production run jobs, I use it in the tail stock seldomly but works great with an alloris tool holder that accepts a moris taper along with a turret stop on your carrage.
