Depends on what server your on, here's a list of the highest priced houses from patch 2.3 made because it has the most players which inflated its economy.
Aegis / Bahamut / Balmung / Behemoth / Cactuar / Carbuncle / Chocobo / Diabolos / Durandal / Excalibur / Fenrir / Garuda / Gilgamesh / Gungnir / Hyperion / Ifrit / Leviathan / Mandragora / Masamune / Midgardsormr / Odin / Ragnarok / Ramuh / Ridill / Sargatanas / Shiva / Siren / Tiamat / Titan / Tonberry / Ultros

If your coming from wildstar its a big jump, now if your coming from Guild Wars 2, World of Warcraft, Dota 2 the transition would be smoother.
But if you can't watch an FFXIV fighting video and be excited it probably won't be worth it.
