New salt tank recommendations

Howdy everyone!

I've had numerous freshwater tanks before and I'm getting ready to try a
sal****er setup (probably fish only) for the first time. What general
recommendations can anyone give me? I want a good size tank (anywhere
between 55 and 180 gallon). What's the best filter system to use? Anyone
had a do-it-yourself wet/dry system? Is it worth my time? How about live
rock, crushed coral, etc? Is there an all inclusive list somewhere that
details everything I will need?

Thanks,

Andy
