If you were finishing up college, I'd advise you to finish and enter the Corps as an Officer but you are in a trade school which may or may not be worth a crap to you in the future, so dump the Trade School and join the Marines. I have never looked back from my decision to join the Corps right out of High School. I used the GI Bill to go to college and have had a very satisfying career for the last 35 years.
Things have changed a lot since I served but I can say with almost 100% certainty that you will live, sleep and eat in facilities that are quite inferior to the other services. You will be using weapons that were probably used in the Vietnam War and ammunition that may even date back to Korea. If you want to be pampered, talk to an Air Force recruiter, If you want the best and newest of war fighting weapons and aircraft, talk to an Army or Navy recruiter. If you want to get your butt kicked again and again in basic training, live with in the most basic of facilities and fight with weapons, that aren't new and shiney - go see a Marine Recruiter and ask them if he thinks they want you.
