Mine is a 30 plus year old Danuser and it has held up well. I do not have hydraulic down pressure and it still works well, albeit a little slower than a down pressure auger would.
My only suggestion is to get a 24 inch auger with it. I use this bit more than any other to dig footings for deck posts, holes for planting bushes, and it works great to mix soil supplements in when planting shrubs.
As for aligning it I found that by using the tractor to move forward/back I can keep it pretty straight. Wiggling a little back and forth also makes the auger bite in and dig better.
