Hi Mo
Can I ask why you don't like the portable bandsaw.
I am heading in exactly the opposite direction to you. The stationary bandsaw is great for smaller curved knee braces but I find it pretty hard to steer a bigger timber through the machine with satifactory results. The curve always has flat spots and uneven radius even with a nice new band on my old 36" saw.
I find I am getting much better results with a carpenters chainsaw. Rougher finish but much fairer curve.
I am saving up my pennies for a Mafell Z5 unless someone talks me out of it.
The stationary bandsaw is still a damn handy tool to have about the shop nonetheless.
Cheers
