I love mine for the price.
Are their stronger units available? Yes. Will I ever abuse one or commercially use one to justify 3x the cost- never.
I reviewed all that I could find, and for the money, cannot be beat. Hidden/protected hoses, one piece tines and greasable jaws were the strong points that weren't on other budget grapples costing $300-$800 more.
Depends ALOT on usage. I only planned on moving brush and tree debris a handful of times a year.
BTW- I got the 60" double jaw unit delivered for $925.
