your cpu is a 2500 or a 2500k? If it's a 2500 than you wont be doing much overclocking so you should be able to find a cheap board easy.
The way i pick a mobo is to gradually apply search filters and thus reducing the number of options available.
First you would select price range, than socket (1155 in you case), than form factor, ATX, mATX (which cut the available options in half), than decide whether you want and/or need USB 3.0 and/or SATA3. That would further limit the options. And just keep adding filters and soon you will go down from hundreds of options to a less than a dozen. If you're a fan of a particular brand, add that too, and you will seriously reduce the available options. (although I generally prefer to be open minded, and not really factor in brand).
