I've been thinking about getting a manual tire changer.  

I have snow tires mounted on/off my wife's car every winter/spring, so it would pay for itself pretty quickly if it works (Hf has for about $40.)  There is also a manual balancer for about $80.  

I'm getting pretty comfortable with MC tire changes using spoons - have never tried a car tire.  

Just looking for a few anecdotes.  (I'll believe the ones favorable to the decision I want to make!)

Quite often, a friend has one we use as needed. Harbor Freight cheapy, they just need to be bolted down securely.

Tubeless radials are easy to inflate, pull the valve core, hit the filler trigger. Seats them in seconds 98% of the time, all the way up into the tractor trailer super singles that are over 400mm wide and 24.5" rims. A little squirt of soapy water around the bead helps prevent sticking and speeds up seating times.

I have a spark plug wire boot on a Milton fitting thats threaded into another Milton. The boot is tie wrapped onto the Milton. I pull the valve core, lube ( OOOOKay, I Spit on it,, allright?) the boot & shove it down on the valve stem ^& plug the air hose in. It shoves so much air in so fast I can almost always seat a light truck tire. Thats whats on the front of the backhoe. I have sealed leaks at the bead with the tire on the machine by hammering the tire away from the rim a little( with the leaky area at the top) & squirting Green Slime in & airing it back up. I like Green Slime a lot. NOt for its flavor or texture on the palate, but for how it helps with tire problems. Rassling the tires on that b/hoe has taught me a lot. I also have a HF tire tool. Ive never needed it for a car size tire, but it worked great on bustin a lawnmower tire off.

I bought one of those H-F manual changers back in '91 when I started racing again. Also bought one of their bed extenders & a hitch receiver. I mounted the receiver to the bumper of my truck on the pass. side & used the bed extender U-bolted to the tire machine to secure it. I don't know how many tires that thing has mounted since we let anyone who needed to use it. The bead breaker is great for m/c tires too.
