cheapest 1151 overclocking motherboard?

Solution
Never used an ASRock board, but that one has excellent reviews from NewEgg users, so that's good enough for me.

NewEgg has a killer price on it too, so I'd snap it up in a heartbeat on a budget for $80. But I'd also look at the MSI for the same price. You can't go wrong with either, but MSI may have better support.

Not sure where you are located, but if you are in the US and you have a Fry's Electronics in your area, they have an ASUS Z170-AR on sale right now for a Promo code event for $119. It's normally a $160 board. I have the Z97 variant of ASUS's -AR series for my i5-4690K it is an outstanding overclocking board with full features for the money.

 
To overclock successfully with control, you need a Z170 chipset. The less expensive H110 motherboards are between $50-$90 but do not have CPU multiplier overclocking...also they are generally the small form factor motherboards (mATX) with limited expansion slots.

The H170 boards are the full sized versions with a little more overclocking support, but can get into the same price range as entry level Z170 boards rendering them not worth it IMO.

You wanna play, you gotta pay.
