Get Wally's Warn XD8000i for $400. http://www.rme4x4.com/showthread.php?92542-Warn-XD8000i-525
Steve, for your purposes as you describe them, I think I'd go with the smallest, lightest, most easily stored and deployed option that has a reasonable chance of actually being useful. Of the options presented, personally, if I were you, I'd go with that Wyeth-Scott unit. It's not as capable as the ARB, but it looks like a lot less fuss to store and deploy.
ok, $11.
I can't remember where, but read a post where someone said their most important last ditch "recovery" tool was a mountain bike to get back to civilization/cell coverage to call for help.
Now that I've started this thread, Karma is going to get me and I"m going to be stranded in a place that only a bumper-mounted winch will help me.
And here's a fun winching story from 2 weeks back. This experience convinced me that I might actually want a real front-mounted winch.
Frieed and I planned a trip from the southern swell (Goblin Valley area) to Capitol Reef/Fish Lake. Part of our route required crossing the muddy river. When we got there, the bank was about a 2-3' drop in. The river was about 30 feet across and flowing at a moderate pace. We measured the depth with a stick and found it to only be about 8" deep. No big deal, I thought, I've been through stuff 3x this deep. Frieed has a winch and a pull-pal, otherwise we probably wouldn't have tried the river crossing (actually, I would have tried it, Frieed would have had more sense and turned around). You can see where this story is headed...
Fried dropped in and even with both his axles engaged he wasn't able to get across. He went about 5 feet, then he sunk to his axles. Fortunately the water was about 2" below the door and the interior stayed dry. We got in the water, drug his winch line out about 60 feet, and used the pullpal to winch him out. There's no way he could have got outta there without a winch.
Then it was my turn and I didn't even make it all the way into the bank before I got stuck. My rear hitch got hung up on the bank entering, and I had to get winched across as well. It was a really unique river crossing. It was like pea gravel 10 feet deep. The water was flowing through the gravel, even 5 feet below the surface. once our wheels started turning, it just dug big holes with the tires and we didn't make it across. I had to be winched across as well.
I still have my hand winch, but I wonder if it would have gotten me out of that situation. I'd rather not find out. I'll still be keeping the hand winch for nasty recoveries and general lifting around the house, but I decided then and there that I needed a front winch. I can't afford the winch or the bumper this year, but I hope to be able to in the next year.
The funny part is that we crossed a deeper water crossing later in the day, but it had a solid and firm bottom, so we had zero problems.
