Bit late to the party, I know. But people saying that Hog is comparable in price have me scratching my head. A Hog set of regs is roughly TWICE the cost of the SE regs, everywhere I've seen them.
I bought SE regs with the intention of slowly upgrading them, because from what I could tell, even if selling them later for half the cost, if you do a dozen dives with them, owning your own stuff, over renting, will pay for itself. If you go on week-long dive trips, you're gonna be paying $100-$200 for RENTAL stuff, that may or may not have been vomited in, isn't going to be any better quality, and when you get home, you STILL don't own any regs.
Buy whatever you can afford, to initially own your own gear, and then upgrade as needed, and sell your used stuff to somebody else at a discount and let THEM save tons of money over rentals, until THEY can afford to upgrade. Circle of life.
I bought my SEs with the intention of upgrading, but honestly haven't felt the need. They breathe just as well as some other people's regs I've breathed off of, that cost 5-6 times what I paid for mine. The hogs definitely LOOK cooler, and I wouldn't mind picking some up, eventually, if I found a screaming deal on them.
The Hogs are nice, because they can be adjusted easily if your breathing feels heavy, but I've never felt that I would have benefited from adjusting them. The Sea Elites have the basic venturi adjustment, in case the start bubbling at the surface, but mine don't even do that, even with the switch left on.
There's absolutely NOTHING wrong with getting lower-cost gear. It beats the hell out of renting, pays for itself, and if you feel the NEED to upgrade later, there's nothing stopping you.
Honestly, the only thing that even SLIGHTLY motivates me to "upgrade" would be the attitudes I get from other people about my gear being 'cheap'. But in reality, I'm more motivated to NOT 'upgrade', because then when some asshat's 'high-end' gear fails, or sits there sputtering all over the surface while they hit it, rattle, shake, and smack it, and play with the venturi switch, and mine doesn't do any of that, I'll just give them a little wink and a nod, and gesture over to my "cheap" gear, and ask them if they want to know where to pick some up like mine.
