Yes WWII kit is hard to come by and expensive and not good for much else. Most people recommend the MP5/AR15/AK47 route for beginners because there are more brands to choose from, more parts to replace broken ones, more upgrades ect.
It is like going to buy your first car and you have the choice between a 2005 Honda Civic/some other generic brand car, or a 1969 Camaro. Everybody would like to have the Camaro but replacement parts, servicing it? That's a bitch. This is just in relation to a weapon you might be able to get on the classifieds once your verified.
tl;dr Get age verified and research WWII kit and modern kit.
