I got MechFansToys' Omega Supreme, so I don't need this. Especially after looking at the CAD CG, it looks like it's missing elbow & knee articulation so far.
I also got Zeta Toys' Fort Max & so you can imagine I want a Metroplex, Scorponok & Trypticon around the same height.
I skipped Hasbro's Titans because of its size (& price post-Metroplex).
