Common small block filter ?

I get Baldwin B34 oil filters from Grainger, about $9 each after tax and rated to 5 microns. If they're good enough for industrial and commercial heavy vehicles they're probably good for my 2 360s and Jeep 4.0L. I've noticed mid-range and "top-shelf" oil filters have gotten REALLY expensive in the past few years, no way I'm paying over $10 for an oil filter unless it's for some special newer import engine.
