more expensive? not here I get 8/4 for around 3.50 a bf.
but it is a little easier to work with and the dust is not horrible. 80% of my planes are purpleheart so I cut a lot of it and seldom is it a problem. one thing to watch for is cross cutting it the wider boards say over 8" can bind the blade. I have jammed blades in it more when I am almost through with my scms. I usually chop through at the back of the board then go to the front and cut normally.
