I have an SGC1560 for my MX and I love it.  Like many here I use it for all kinds of purposes.  I have lifted large logs that maxxed out my lift capacity, moved large rocks, use it like a forklift with a couple of stout straps, and have yet to hurt this thing.  My only complaint is the weight of the beast, it comes in at a whopping 820 lbs!  IMHO, that is one of the biggest advantages of the EA product.  I also love the customer service at EA, I purchased a auger from them and everything about the purchase was top-notch.
