My "weekend warrior" status puts the grown man box blade that jenkinsph has in the "hard to justify for me" class, so I got the Deere BB3272 for $1600. It weights 800#s, 21 cu. ft capacity, and is heavy duty enough for my JD 4520 60 HP tractor. I'm working on a Top and Tilt (TnT) which will make it even more useful. Yes, I have to get out of the cab to take up the scarifiers but so far I'm happy with that trade off. I'd love the bigger box with hydraulics, this works for my use and the "soil" in my area (red clay)
