Thanks for the replies, guys!
Ed, that was a suspicion of mine, especially having worked with other kits that were copies of kits by other manufacturers (eg, HobbyBoss' Arizona in 1/700). I'll think a little harder about buying the MHM kit. In the meantime, there's another Tamiya kit up on eBay, who knows, maybe I'll win that one.
I'm not too worried about correcting details on the Tamiya kit. I like to tackle things like that and flex the scratchbuiling muscles. But when you get to details that are soft because the kit's a copy (or a copy of a copy), it becomes less of an enjoyable exercise and more of a chore.
Mikey, you're right, too, I'd like to see a new kit of the Enterprise, accurate to a specific point in time, or maybe, with appropriate optional parts to build her in some of the various refits. Maybe a kit that could be built as the Yorktown, too, there's no 1/700 kit of her, either.
Well, in a couple of hours, I'll know if I have the Tamiya kit, or if I have to keep watching
Thanks again, and best regards,
Brad
