don't get a hex, hard to clean, hard to aquascape. A standard 55 would be much easier, more swim space for fish too. Personally I would get a All Glass 90g or 120G. just get a good skimmer and some live rock and metal halides and your are pretty much set. See if you can find someone breaking down their tank, buy rock from them and you can have it up and running in a few days. Or else you have to cure the rock for about 3-5 weeks depends on how cured the rock is. hope that helps. Oh yeah, the bigger the easier, but more $ as well.
