Review on Barn Leveling 🏗️ Machine with Retractable Casters by Dave Neal

Reasonably priced (design is a copy of British Footmaster design). It's surprisingly easy to ride, the only downside is that the bolt the block mounts on could be a bit thicker. It has no problem supporting my machine's weight (its 550 kg/1250 lbs), but since it is a reciprocating shaper that moves horizontally, it does move a little. For a heavy precision machine, it would probably be better to use rollers to lift, roll and hit hard points.
