I'd say buy your wood at the best place for you, in the price range you can afford. I take it you have your print's and build table ready? and some needed tool's?Personally I'd look over your engine choice now and put effort into getting it on hand along with FWF item's. There are many engine type's to choose from. Many thing's to gather up for your plane. Wheels, tires, Ect. Check with Aircraft Spruce or other suppliers too see if they have precut spruce kit's for wing's and Fus. +1 with what Victor Bravo said in his reply, it's always nice to talk, look, and touch another's builders project or finished plane. Good luck and patience on your build you should have a blast!!
