If you were able to get it at the minimum bid, it's not a terrible deal. Hasegawa 1/48 Zeros are running $30-$35 new at the discounters, depending on the boxing. These would be less than $30 each, and you're getting a few unique kits, along with the prints and figures.
That said, one still would need to be a super diehard Zero fan to want 15 of them. Even modelers with an interest in the Pacific War probably don't want/need that many. I built the Tamiya 1/48 Model 32 & 52 kits when they were new a few years back , and that was enough for me.
