i just purchased my second pair of these adjustable stanley horses. i've had one pair for 10+ years. about a month ago, i broke one of the expandable wings and just last week purchased my second set. THEY ARE PLASTIC, NOT WOOD. i'm a diy'er and have used my old set for many things i've build, including a 8'x12' garden house for my wife and a 'to code' handicap ramp for my MIL.
i love them because they're adjustable. would i purchase them again - yes.
