Is there such a thing as buying precision cut lumber? I have had extreme bad luck with having plywood and mdf cut at home depot. The don't guarantee precision cuts and usually it's not even close to a straight cut. I'd like to buy some mdf for a new project and would like to have it pre-cut since I don't have a lot of space to do it in my apartment. Not looking for crazy detail work, just a few straight cuts. Anyone have any recommendations?
