I hear you on that. I'm seriously considering getting a bandsaw mill at this point. Higher cost entry point, but total cost of ownership has got to be less, especially if you factor in how much your time is worth. (Hint: you'd better be paying yourself at least minimum wage. Lots of people aren't).
I spent a good 3 hours Saturday trying to mill up some Black Locust. Trying was the key word here, because for all of that effort, I ended up with one 6' long slab, 24" wide, and 4" thick. Man that is some *heavy* and tough wood!
I ran out of daylight, the logs were too big to move (and had to be moved Saturday), so I ended up chunking what was left into firewood.
