I love this thread!!!
I havent dived for ages and coming back to diving (I left when the Mk25/s600 came on the market), I am trully impressed by how things have advanced. Well... Okay, most things are the same... More shiny, a nicer finish, lighter; thats all i really see as a diff..
My last dive was a few weeks ago at Manado. Lovely dive... Had the pleasure of using my Oceanic Omega 2 paired to a pre1986 Tusa Balance Piston 1st stage on the first few days.
Subsequent days were spent suckling ona MK25/S600..
Difference? Err... Quiet a few hundreds. Besides that, I prefered the Omega two.
So here is my point, there really isnt that much difference between the kinds of regs out there now. Granted a balanced vs Unbalanced system will definately see bias; besides that, manufacturer to manufacturer - nothing significantly diff...
Get the best you can afford, dont get ripped off in the process, make sure it works, make sure you look after it. And for goodness sake, looks really dont matter all that much... for Reg at least...
Now BCDs: Eh that one no same same... Skill tadah, style adah!!! Boleh?
