Ok, so, been looking and reading and thinking more.

These are my three primary contenders:

(Order alphabetical only)

--HMG Southwest 3400
--ULA Catalyst
--Zimmerbuilt ZB2 with custom layout

Anyone have any reasons why I should choose one over the others? Yes, the Catalyst is a pound heavier, but it looks to have an awesome-well designed backpanel and suspension, which is most of what's keeping it in the running.
