One-off price is about US$1400 ex Sydney Australia.
We can ship internationally, we sold some into S Korea recently. It weighs 26kg (that's 57lb for the metrically challenged) and it's about the size of a large hand truck at 1.5 metres tall.
If that seems light, remember it's almost all welded aluminum. The early ones were steel and weighed over 60Kg!
Make sure you tell us if it's going to a 110v country, standard P/S is 240v.
Battery holder (not shown in pics) is for Makita 18v Li-Ion.

Currently these are built in small batches mainly for our own dealers, we can probably do a better price for larger qtys.

I don't see a market for a TV lift. 10 years ago when plasmas were the tv of choice, sure. But now when a 65" TV weighs under 60lbs, it seems like more of an annoyance in most cases. And in the few cases where it would be handy, it doesn't go near tall enough. On a recent project I had to hang two 65" panels on arms, where the bottom of the panels were over seven feet in the air. There I could have used a lift. Trying to position two 10' ladders so both of us could carry the tv as we climbed the ladder was a bit tricky.

Yes I agree with you about smaller panels.
However....
Try installing a 104" screen with less than 4 guys! Very expensive if you drop it.
Then as well we have OH&S (Occupation Health and Safety) laws here Back injuries are usually irreversible and costly.The first few inches of lift out of the packing is where most of the damage is done.
With one of these a two man team can do 15 classrooms in a day with no risk of injury. One guy does the bracket install, the other the screen lift and prep.
A grand or two is cheap insurance!

I would have thought that 8 years on, the OP would have worked out how to hang their screens, or retired with back injury by now.....
