let see
Regs- either the Posieden Xstream or Zeagle Flathead 7
Rebreather- Dive Rite O2ptima w/ Hammerhead computers
BCD- I have two of them and I think they are both tops. Aeris Atmos XT - for warm water and Hog Gear stainless BP/W with Hollis Elite 2 Harness for cold.
Drysuit- White's Fusion, the new Bullet fixes the only minor issue I has with the Fusion
Wetsuits- Pinnacle
Computer- I like the Oceanic VT3 as I like the large screen and available information, but there are lots that are very good, I have seen but not used the LiqiudVision X1 and it appears interesting.
Fins- pretty much only use Force Fins, primarily the Excellerator Tan Delta with Batwings.
Tanks- depends on the application, I think for warm water recreational diving (Red Sea) there is nothing wrong with the cheap AL80's, but when I slip the drysuit, steel is the only way to go, I can't say anything bad about the Worthington, I have seen too many HP Faber's fail their first hydro. As for size and HP/LP that is up to you, lots of pros and cons there. For recreational diving I haven't found that I need over an HP100, its light weight (essentially the same weight as an AL80, even if buoyancy is very different)
Lights- I was going to say on of the Solus can lights, but I think they went out of business, so something in the 24W HID range.
