I'm almost in the same quandry, there's too much choice, but for my money out of the ones you've listed, it'd be the D44 one, nice and tight fitting, and i personally like the idea of the winch being out of most of the weather, daft i know, i have been looking at the Golddigger one, which seems good, and is even tighter fitting...... he also makes a steering guard that bolts to the bumper... i think this is the option i will be going for..... and if i feel the need, i'll also be getting one of his rear winch bumpers aswell.... although i'm still not convinced i need a rear winch.....

PS< best to make sure that it'd fit IF you have aircon etc..... sometimes you might not want the winch set so far back....!!
