Hand truck. What do you have and do you like it?

My personal model is the former $29 HF unit (now $39).

It has also been converted into a transformable yard cart to be pulled behind my riding mower.

It has held up very well for over 14 years, but the pneumatic tires are a weak point.
I have to add air nearly every time I use it.
Flat free upgrade is on my list, but it's easy to spend more than a new cart on a pair of decent tires.
