Have you tried reverse searing your steak?

1. Bake oven at 250 and pull when it is 10 degrees below your desired temp.
2. Just before you pull it melt some butter in a cast-iron skillet over medium-high to high heat.
3. Pull and sear on all sides.

Let it rest for a few minutes and bam, perfect steak every time! 

 I have actually! I ended up cutting out the oven though (just to save a step) and started searing then basting with butter on the cast iron skillet. Got pretty good at getting it to the desired temp through that method after some trial and error.
