"Opinions on all the lifts....."
After deciding what you want a lift to do for you (easiest way to rule lifts out of the running) it gets a lot simpler to look. For instance if the SD64 were tall enough and narrow enough for most of my work it would be a slam dunk decision as it looks so fast in getting to set up spots and etc. But alas....
I think it's definitely worth talking to Upequip about their Easy Lift models if any of them suit your needs. Their after sale support is legendary among the owners - quick call backs, diagnose by pictures, email, video. Work you through till you're up and running again. And their motto "simple inside" is a reference to no computers etc. All their safety sensors etc are switches and electrical impulse that can be checked for at point a, b, c. under their instruction. Back up and running, job done.
The other thing I would say is whatever lift brand or models in a brand you settle on try them out before buying one. I tried about five different brands and just using one for a few minutes demonstration was enough for me on some of them. Also even if you settle on one brand as a preference one model to another can be quite a bit different.
I'm annoyed by wind movement in a tree enough that some days I'll bag it and stop for the day if too windy. The 70 ft Easy Lift has a fair amount of sway at full side extension (30 ft or so). But the 101 foot model had far less at 48 feet of side extension. (The booms are shaped differently. )
