I am looking forward to starting my own reef tank. I want in to the salt hobby more for the corals and inverts than the fish.
I'm just too busy this year, but if I have some downtime in the next 5 years I will be taking the plunge with one of my 75 gallon tanks. The current residents of that tank are elderly and should finish out their natural lifespans within the next year or two I'm guessing - then it's time to convert!

Expensive equipment (lighting, etc) but worth it IMHO~
