I don't think brand name is too big a deal, unless you choose to make it one. Zeagle, Mares/Decor, Sherwood are all good stuff. Purchasing online will save you money now and cost you money later. My LDS is higher than most online shops, but he services all the equipment free of charge for the life of the equipment. I live in the midwest and only get in a few dives a year. Each year, before I start diving, I can go to his shop and jump in the pool with my equipment. If I encounter any problems, he fixes them free of charge (I pay for any parts needed, but labor is free). That's worth a lot to me, more than the difference in price I paid for the equipment. Also, he knows my equipment as well as I do. If/when I decide to upgrade, he gives me a good price on trade or helps me get a good price for third party sale of my used equipment. Additionally, he knows what I need to dive local & the tropics. Lastly, I can try out anything in the shop free of charge. Work with your local dive shop, try out the equipment in the pool and make a decision from there. A good working relationship with your local dive shop is worth a lot in terms of money, time, and confidence in your equipment. I agree you should have your own regs and bcd, especially if you plan to dive 3rd world countries in the tropics. I've seen some really crappy rental equipment in the Bahamas and Mexico. Weight integrated is very nice and so is pnumatic dump bcd (you hit a button at your waiste and all the air dumps at once, on your way to the bottom, no delay at the surface and no tying up one arm above your head dumping air). Back float vs jacket is a personal decision. I like jackets, some like backfloats, no big deal one way or another. As for ease of packing for travel, all dive gear is bulky, some a little bulkier than others, but again, no big deal. That would be among the last of my considerations. I'd rather have a big ol' bag full of stuff I like and am comfortable with than a slightly smaller bag full of stuff that's uncomfortable or that I just don't like. Suits are easy and cheap to rent. Try a few, see what you like and then decide if you want to buy or not. I've been diving 11 years and still don't own one. I have family in the keys like you do and don't need one there. Hard to get excited about muddy bottoms and bare rocks at home once you've seen the keys. I do dive some at home, but in 11 years I haven't paid enough in wetsuit rental to pay for one. Good luck in your quest for the right stuff and welcome to the sport. Be safe and have fun!
