My way of thinking (mind you, this is why I DONT have a winch; I cannot afford it at this time!) is that if you are going to invest in one, get a GOOD winch... To me, that is either Superwinch (a bit cheaper, but still reliable) or Warn (the best).
And the reason is this:
Even if you use your winch once every two or 3 years, most likely the reason you will be using it is because the S$&t hit the fan and you got stuck in the middle of nowhere. At that point, I would much rather have the confidence that the winch will (1) work, and (2) will have enough strength to pull me out of the situation (no matter how bad) so I can get back home. As a result, I prefer to wait and save some money, and buy me something that will bring me this peace of mind. Until then, I will be either doing some VEEEERY light wheeling, or depending on the winch of others to get me out of tough situations...
And another comment related to this (this is kind of the advised I am not following myself, if you know what I mean): a good winch should be one of the FIRST mods to be done. The reason for that is that all the other stuff (lift for bigger tires, bigger tires for more grond clearance, rockers, armor, more engine power, etc.) are things that will give you confdence and actually help you get stuck in the first place!
Think of the winch as an insurance... You invest a lot of money in it, and hope you never need it. But when you do need it, you REALLy want it to do its job!
