I've actually still got mine in the box... Going through a bit of buyers remorse actually for the first time with a DX. I had mine reserved at Joshin here and was happy to be able to use a 5% off bday coupon, but looking at what you get with this (very bare bones) versus the Focker Armored that is the VF-1 plus armor parts for just a couple thousand yen more and I really feel like Bandai randomly price gouged with this release. Then I note that stock is overflowing and you can get it for 30% off from 3rd party resellers already on Amazon JP. While Delta releases tend to sit on the shelf longer than Plus or SDF versions, I am surprised that 7's DX wouldn't be popular... Then again seeing how much HM-R stock is sitting around, I should have known.
Regardless, price gouging aside, Wotofa is calling it the best version, and I don't have any of the Yamaoto's, so at least I can say I have one for the collection. Now to wait for the inevitable PreBan release of the sound boosters....
