Finally got a thickness planer.
I picked this one because it was priced about where I could afford it, and it wasn't from Harbor Freight. It is an Asian Import, but it works very, very well.
It's a Porter-Cable PC305TP. It's a 12" thickness planer, 2 blades, 15 amps.
The knives are high-speed-steel and of the quick-set variety, so you don't have to do a lot of dicking around with adjustment wrenches. They're are also double-edged and reversible, so when you wear one edge out, you just flip it to the other sharp edge and you're back in business.
So far, I've made a few neck blanks and planed some hickory down to thickness for bow making.
It seems to be a good, solid tool. It came highly recommended by a few local cabinet makers and a couple of non-internet luthiers I know personally.
Incidentally, I got it at Lowes for $269.
