I have several of the ones from Walmart (usually in stock around this time of year, I haven't looked this year though). Like $99, 15 foot ladder stands. Been hunting in them with my oldest since he was 3, wife took her first buck sitting next to me in one a couple years ago. Always worked just fine for us.
As noted, they can be kind of top heavy. If you set them up with the ladder base against the tree and the seat face down out away from the tree you can lift just the seat and sort of "walk" it up into place. Lift, take a couple steps, grab the next rung down on the ladder. Repeat until the stand is in place, then just pull the ladder base away from the tree a few feet so that the seat sets properly against the trunk. Adjust and secure as needed.
Been hanging them myself with that method for years now and I've only had help a couple times.
Large branches seem to be difficult to avoid, so bring a saw.
