I would not trust the princess thing, it is installed on a simple round head jack, with narrow wheels, ever hear the term "top-heavy" ? I think you'd need to keep hold of that thing in keeping it upright and balanced.
They offer me no loot to speak of their transmission jacks, but the FH/HF whoever the **** is at least stable and offers more functions that just transmission, it is also a valuable tool to use when lifting the Transfer Case, with a simple 4x4x8" the TC is held in perfect position to bolt right up.
All of these being held from falling off by a built in strap, on a machine with wheels far enough apart to keep it from tipping, even while wrestling with alignment.
I won't touch on other options here, although that might be fun
