At the price where it is at now, I would not be surprised to see somebody kick it up by a few bucks hoping to outdo the competition and get it for close to what it was originally available for price-wise. The problem comes when before you know it, your $100 higher, then $150, and on and on. You think, "Heck, if I'm going to spend $815, what's another $10." You then repeat as necessary.
You should try living by my rule, which truthfully is not easy, but it is simple:
If you voluntarily passed it up when it was available at X price, don't change your mind later and pay X plus $$$ just because you changed your mind. In other words, make up your mind when it is first available, and then stick to your choice.
