Swamper, listen to "dee". Also, my two cents. Forget the drysuit. Given your size, buy a conventional 7mm wetsuit but do it through your local shop. Get a custom fit if necessary. Stay away from costly hype like "titanium" and what have you. Don't get add ons which stiffen the suit; I'm talking kneepads, under garments etc, unless you are going into salvage.
You will probably be happier with a recreational back inflate BC. However, take a look to see if it is cluttered with add ons. The front should be clean. Extra dump valves and weight pockets are OK.
Mares and Aqualung make good recreational to advanced regulators and are discounted. Easy to find dealers/service.
Go ahead and splurg on a pair of split fins such as the Apollo Pro or Scubapro twin jet. Allow for wet suit boot.
Try the SP Frameless mask or cheaper imitation. Black rubber is good. Be prepared to use anti fog for the first six dives.
The Genesis computers/gauges are easy to read and reasonable. The graphics are outstanding. Everything in one console except compass. That should be a wrist type with a revolving bezel and marker.
The aluminum tanks are cheaper. Steel tanks are more compact and are negatively buoyant which some folks appreciate.
Straightaway, decide on the type of connection, the high pressure DIN or the standard yoke type.
If you have some hidden agenda, such as becoming a "tech" diver, forget the above.
