I'm getting mine via HLJ and I've paid for registered airmail as it was significantly cheaper than DHL, and I've been hit with a triple whammy with MP Hoist, MPG Kaen and ML Convoy all back to back. It may be up to 6 weeks before I receive mine, so I'm just living vicariously through other people's photos. I've yet to see someone post a side-by-side comparison with an original G1 Optimus Prime, but here is a comparison photo with Music Label Convoy - which is basically a reissue original G1 OP with a new head.
