I have finally decided to switch my Bandai Fix Figuration #0013 EX-S back to the PLAN 303E Deep Striker mode, and I can't say it's not a masterpiece. The whole Fix Figuration serie is excellent, but this one is truly fantastic. The detail is amazing, true to the concepts, with good paint/ink application a incredibly detailed markings.
The cannon is huge : 42 cm/ 19" long ! It's the most expensive of the serie but you won't regret this investment, it'll attract all the attention in your showroom. I had to put very small superglue to help, because some parts are easily lost (shield, small parts on the boosters), but all main parts are well held, the toy is well engineered, I've switched from EX-S to Deepstriker 3 times and the joints are still strong, good quality of soft PVC. My only complaint is that I coudn't find a way to raise the handheld beam cannon. If you're interested, Ebay has often some for sale.
