I just bought a 4 ton comealong from the local 'Tool Store' to remove my stump after severing all the roots I could find.
I think it was regular $59 on sale for $29, the best they had. The release never did work right out of the box. There's a little aluminum bolt on a spring that's supposed to push the ratchet out of the way, but it just kept getting bent. The winching seemed to go fine, except I noticed that the rivet that the third hook attaches to had popped loose. Fortunately the tension kept in place, so that the cable didn't snap loose and take my head off.
So I was looking around the net for a better version, but they all pretty much look like the one I bought. Some are $8 on eBay, cheap is not what I want in a comealong. The stump is out BTW, so it's not something I'll need until the next time.
