Here are the expected prices for the LGA1155 boards from Gigabyte. The listed price is in British pounds, which I've converted to $US based on today's rate:
Gigabyte P67A-UD3 - £99.99/$157.37
Gigabyte P67A-UD4 - £149.99/$235.97
Gigabyte P67A UD5 - £209.99/$330.33
Gigabyte P67A-UD7 - £249.99/$393.26

Of course, the $US prices are only approximate, since the exchange rate fluctuates, but it provides an idea as to roughly where the price points should be.
