I got the 3.5 ton Arcan from Costco for $99.00 Costco item #300930
I have the Craftsman 50145 3.5 ton.
Arcan: weighs 101.41 lbs, rubber pad on lift cup, universal joint connection to operate release valve, side plates 0.30 inches thick, grease zerk for lift arm axle, low height 3.5 inches, high height 21.375", 7.5 strokes to full height w/o load, padded sleeve around handle to protect vehicle. Looks like a decent jack, hope it lasts for awhile.
Craftsman: weights 82 lbs, no pad on lift cup, gear connection to operate release valve, side plates 0.23 inches thick, no grease zerk, low height 5.75 inches, high height 20 inches. The Craftsman has a one stroke no load quick lift to 17.75 inches and a rubber grip for the handle, which were its only two advantages. Not working is its major disadvantage.
I was able to remove the rubber hand grip from the Craftsman handle by gently heating it with a heat gun and tapping it off with a wood block and hammer. I then sprayed the inside with silicone and used the heat gun, wood block and hammer to put the hand grip onto the Arcan handle, which I measured at only about 0.04 inch larger OD than the Craftsman handle.
