That new Jackson looks a lot like my vintage Craftsman with one wheel.
I've had this one for at least 20 years and have replaced the handles twice, welded new metal where the bolts go through and coated the inside with POR-15. The last time with the handles I just bought a pressure-treated 2x4, ripped it and rounded the ends with a sander. Its been a workhorse but I'm so used to a two-wheeled one that using a single-wheeled one takes some readjustment in technique.
