I don't think that quote is out of line. We checked into their systems a year or two ago and the price was similar then, depending on what you opted for.
We decided to hold off and see if we would get better at leveling as we used the rig more. Indeed we have (or we've just become better at picking level sites
). So for now we've stayed with our blocks and it works fine. Lots of places we can spend that kind of $$$.
