I agree. I put the pics side by side and I cannot tell the difference. Reading the descriptors, there are a few minor differences:
Sears - $149.99
Lightweight aluminum construction- weights only 44 lbs.; Low profile 3-1/2 inch clearance extends up to 19 (with Adapter Bars). Ideal for oil changes, tune-ups, clean-ups and more. Can be used as a dolly to move vehicle to convenient location for work or storage. Four position locking mechanism engages at 7, 11, 13-3/4, and 15. Rubber padded saddles resist vehicle slipping.
Harbor Freight - $139.99
Lightweight, only 60 lbs, high quality aircraft material. Rapid Pumpâ„¢
High strength, lightweight aluminum stand looks great in your garage, is ideal for servicing motorcycles, ATVs and other equipment.
* Platform goes from 4-7/8'' off the ground to 17-3/8''
* Rubber grip pads on saddle protect motorcycle case and frame

I'd save the $10!
