Congrats on your decision! i myself just went out to ohio about 2 weeks ago! it was a great whirlwind trip. left wed. night, and got there early in the morning. there were only 2 people in line. so first off, get there early, cuz they usually open a little early. second have all your paperwork done when you get there. it's a whole lot easier. there was a guy there when i went that didn't have all his ducks in a row. he went through the racks, found 2 rifles he wanted and then found there was a problem with his paperwork. he couldn't get them. so make sure you have it all done.
i got a great SA field grade (which is all they had--but a lot of them). i pretty well lucked out. wasn't expecting to find a ww2 but i searched the racks for a low serial #. wound up with a 797xxx! it was made in august 1942. shoots perfectly for a 67 year old rifle!
hope that helps a little.
