Okay - so I disagree - I have a #7 hoe, and it works great for what it is designed for. I've done a ton of work with mine, and while there are things I haven't been able to do with it, there are things I couldn't do with a Cat 416 either.
The 47 is an improvement - a little different, a higher relief valve setting, and therefore higher overall forces, but essentially the same design.
If you are looking at other makes, be sure to check out all the specs, not just the bucket forces.
Higher force means slower speeds for the same flow rate, or requires higher pressures. The pressure is limited by the tractor, regardless of what the backhoe limit is set at, as is your flow rate. The aftermarket backhoe may be rated for double the force, but if you can't develop the pressure or the flow, then it is just slower.
I like my #7 hoe - I'd buy it again. Cheesy is certainly not the term I would use to describe it.
