I did a good bit of research before I bought scuba gear for my son and I, and we ended up ordering this package a few years ago:
Buy Scuba Gear Value System Package at Low Price | Divers Supply - this is a great economical option that is cheaper than many used sets (especially when you add $$ to have used gear serviced/inspected by a dive shop). Sea Elite is just Divers Supply's store brand on Edge/HOG gear, which is good gear. So, any Edge/HOG dealer can service them, though Divers Supply makes it easy and quick to send in for service (they'll send you a UPS lable), and for Sea Elite gear Divers Supply will provide any parts necessary during maintenance for free.
Check out the other reviews on there also. We did 2 upgrades from their options: (1) we upgraded the Regulator to the Covert regulator - which is balanced, so can breathe a bit easier at depth (deepest I've had it so far is 122 feet); (2) we went with the 3 gauge SPG - which adds a compass to your gauge console, so you always have one with you.
We also separately bought the Mares Puck Pro+ computer that they offer as an option on this package -- a basic one-button computer that performs all basic functions that a recreational diver might need (works fine with Nitrox also). One button can be annoying at times, but overall a nice simple computer that works fine.
Extra tip: If you create a Divers Supply account and then put the package in your shopping cart, and then leave without buying it -- they will usually send a 10% off coupon to you in a day or so, which is a nice chunk of change off.
