Bring the family down to Denver! WOZ, DI and Hobbit are all on route here, and well maintained, so you can try before you buy.
The logical thing would of course be to wait til POTC ships, try it, and then decide.
But if you want a machine now, then buying a HUO Hobbit might not be a terrible idea. I don’t have enough games on it to say how the gameplay will last at home (everyone seems to have strong feelings one way or the other), but it’s a beautiful machine. HUO prices are good right now ($6-6.5k) and even if they drop a bit more, it’s hard to believe you’d lose much if you decide to flip it in the spring and pick up a POTC.
Good luck!
