It's all cast iron isn't it? This one has the same rope length as the standard and is made in the USA with the same pull rating.
Tuf-Tug Cable Hoist Puller, 6,000 lb. Pull Double Line - For Life Out Here for $180.
The pull length on the wyeth-scott are either 10 feet or 17.5 feet. They have 20 or 35 feet of rope and are used as a 2:1 pull so they'll pull the load half that distance at the rated capacity. I'm sure they'll work in a pinch. Just like a manual screwdriver works pretty well. It's just a matter of how much manual labor you want to put in. They're slow and require a lot of work. I have a couple of the smaller come alongs for utility work. If you're stretching a fence they work great. If you're looking for vehicle recovery, you can buy a small electric winch for less money.
For example this electric winch has more rope, more power, is portable, is self contained in a nice box for storage, and costs $100 less.
