I have a Quadratec Q9000. It's about 15 years old. Still working fine. I changed the cable for a synthetic cable just this year. Easier to manage and not as dangerous if something breaks. Only cost about $85 for the new cable. One suggestion - If you get a wired remote, might want to consider buying an extra remote while and if it is available. They only cost about $35, unless it is a warn, then about $85. I cannot find my remote. So, since it is only a DPST switch, I made one, and then (after I could not find one from quadratec - always back ordered) I bought a Mile Marker remote and changed the connector plug. I could have just bought a wireless remote accessory, but I kept reading they have a delay after you switch. Also, if you get one with synthetic rope they seem to be about $200 higher initially which is a more expensive rope. The cable I got was rated at 23800 #. I like the synthetic because it is not supposed to recoil back on you if something breaks.
Also, you will find online charts that tell you how much rolling weight at different upward angles (loading trailer) can be pulled by different winch ratings.
Best wishes, Larry
