I had to go back searching for what you're referring to. I don't see any mention of $160 for a 48th scale X. (Right now, the FM kit is on Amazon--yeah, still--for $81 with free shipping and the Bandai is $95 with Prime).
And even though I'm right there with you wanting larger scale kits (if Bandai does a 48th scale Y, I'd get 10 just to start off and e-bay my SS Y), but it's almost like complaining about the scale of Bandai stuff is a lot like the old complaining (pre FM) about the detail and accuracy of the old MPC/Ertl/Amt stuff. Bandai is making some money, and using a little of it to use as earplugs. They just don't care. People say it's a home market issue, but I don't care about the reason. They're stuck making these too-small-for-me kits. And when I said "I bet they come up with some larger scale stuff now", Bandai responded with 144 scale fighters! Ugh!. (Here I need to insert one of those Charlie Brown characters getting frustrated.)
