If cost is not an issue, I would look at Rinehart. They make the most expensive 3-D targets out there, but they last a long time (and replacement vitals are cheaper than McKenzie). Many clubs that run 3-D shoots are switching from McKenzie to Rinehart (I believe Rinehart was used by the IBO for all their shoots last year). Durability makes up for initial cost, and it's much easier to pull arrows from Rineharts too.
