Pump the brakes Pistol Pete! It's your money, spend it how you want. My advice would be get certified first. There are some that have great difficulty equalizing and may not be able to dive.
A travel bcd may be a little lighter, maybe a smaller wing, fewer connection points, and pack a little easier. Big. Friggin. Deal. I can get a full set of gear and 3mm full suit , along with a weeks worth of clothes in a large, but airline legal, suitcase. Regs, computer, and maybe lights go in my carryon.
I could probably get mine in a large carry on unless a gate nazi wanted to make sure it would fit in the little square. Fins take up a lot of room no matter what you do. A travel bcd is mostly marketing hype.
I dive a softplate and wing, wife dives a women's jacket type bcd. Both sets of gear fit in the same size suitcase and weigh less than 50 pounds. That's about as travel friendly as it gets.
Right now you don't know what you don't know. There are hundreds of options beyond jacket type, back inflate, and BP/W. Beg, borrow, and rent umtil you find what is right for you. Lots of people don't like a back inflate and prefer a jacket type for a reason.
I spent a lot of money to figure this out, probably 7 to 10 Glocks worth, and that was buying mostly used gear.
There is actually some pretty mediocre diving in Oklahoma, sometimes bordering on good. Elmer Thomas (outside of Medicine park) had great visibility most of last year. Tenkiller has has 20+ recently but cold. Athens and Tyler Texas have Scuba parks as well and may be more driveable for you. I've heard of some abandoned quarries in SE Oklahoma with clear water, but have yet to find one.
Welcome to the addiction. All that money isn't going to spend itself and you can't find ammo anyway.
