Im with Achipmunk. Its not rocket science. If someone has a planer and good table saw,thats pretty much all you need,plus the wood that youd pick out yourself. Id guess around 200.00 TOPS. And then whatever the stainless strips and bolts cost you.
It doesnt have to be oak,theres lots of species out there that work well for bedwoods. Shop around,Trev.
Good luck,im sure it will look good,whichever route you go.
