I'm with JL on this, pay the extra nickle.
Once upon a time the diff. between budget and commercial was size and condition of knots or woodwork irregularities. Now budget gets its own grade of wood, the open ends on the box cuts look like larger cells and more rapid growth.........if you dip your frames might not matter though.
imo its a nickle well spent for the diff. in what i got years ago and what i got last yr.
