I recently bought a Stanley #4 for ~$60. Upon inspection, the three most outstanding things were that the tote screw didn't fasten the tote down very securely (even if you tighten the screw a great deal), there's a small chip on the corner blade holder (the one oriented at 45 deg) about half the size of your pinky finger nail, and the lateral adjust is hard to rotate (I tried putting WD400 on the rivet but it's still gummy).
I was wondering if I should return it. I'm not sure how important, difficult or costly it'd be to replace the blade support or the tote/tote screw.

The plane is otherwise in good shape.
