That makes two of us, but as a first attempt it won't be anywhere near Steve's, but got some material to play with first.
For the WWII US Gato's, if you step back from the nukes, take a look at the AFV offerings, pretty good detail, and not much flash, and come with some PE. Not too bad on pricing on the '41 and '42 at around $15-20, the 43 is around $35.
