I got what I consider a great deal on a used 75g tank, so I'm pretty much married to that size, what with a fairly limited budget...
I want to have a nicely-populated (properly sized, of course) with corals, gorgonians, etc, plus fish...
Having said that, I'm also not married to the Caribbean, but with my wife maintaining her own 29g, I want to diversify.
I don't want to set up for GBR, but Hawai'i is an option; my primary goal is Caribbean or Gulf of Mexico (I know I didn't specify this in my original post, but it's been on the table...)
