I have an older Champion 8000lb winch I bought from Costco about 5 years ago. I figured it would last me long enough to see if I actually needed a winch, and to my surprise, it is still working for me today.
I have had to repaint the body of the winch and replace the fairlead, but i am sure a lot of that is due to the harsh Michigan winters. I don't know much about the actual one in your post, but I am pretty impressed with mine. Just my $.02
Oh yeah, and if you look at the stats, the reason they are there is that winch is using a 3.6 hp motor, Warn is using 4.5 hp motors in almost all the winches i could find. I can't see how champ is getting better results than warn could even at the sacrificed line speed there is just no way that thing will last. I see it as being over worked right out of the box, it would be like driving your jeep everywhere at 3500 rpm in third gear eventually its gonna go.
I'd suggest spending another 150 bucks and get a warn m8000. The two stats you should look into is the line speed at full load and the amperage draw at full load. The warn will not have to work nearly as hard to do the same amount of work in a given time. Walmart is the devil anyway.
I have a champion 8000lb on the front of my tj, and although some people speak badly of them, I've never had an issue. I've used mine for numerous recoveries including myself and others without a hiccup. A buddy of mine also has the champ on his tj for over three years and just the other day he used it for about two hours straight, pulling both him and the log splitter he was towing behind it from a shed to a house, in 3 feet of snow. How it didn't overheat I'm not sure considering it's not thermometric. However the point is don't base your decisions off of negative experiences only, you might be surprised with the quality of low budget items.
My parents got me one of these for christmas. I havent installed it yet but I did some research on them before they made the purchase. From what I found, Sams has a lifetime gaurantee on the items they sell so people were saying just take it back if it ever fails. I saw alot of people saying they would wear out cloths and take them back years later an go get replacements at no cost to them.
asking about a winch on here is like asking "which is better chevy or ford" there is always goin to be people who say just save more money and buy a warn, then they will throw some stats out there. yes, warn is a good winch but it is also an overpriced winch IMO. there are also people who are goin to say buy a smittybuilt, also a good winch but more in the reasonable price range. it all comes down to what you want.
