If you are designing for 3D, the Magnum is very heavy for it's power output. Saito 82 or 100 is way better depending on size of the design.

There is a few designs out there but the best one was the OMP Boxxer.

The mods here are too immature to allow links to other sites, so here is the only one I found here.

A google search for OMP Boxxer will turn up a few good links.
