Unfortunately, if USS Texas is released by one of the Japanese companies, the price tag would be up there with ISW's, but the ISW kit would probably be better. Look at the price tags attached to Tamiya's Yamato, Hasegawa's various battleships, and Aoshima's prices ( a little more reasonable). If Trumpeter or Academy were to manufacture the Texas, we could expect better prices. But, when considering the price of the ISW kit, it already comes with brass gun barrels and photoetch detail parts, including all railings. Most builders would probably purchase those separately, further adding to the price of a plastic kit.
Since I already have the ISW kit, I would probably not buy another Texas just because it was plastic (unless it were of a different period!)
