I need to buy a 3-ton floor jack and after doing some research, I settled on two jacks. I chose 3-ton because I might need it for my wife's 4,000 lb. SUV. Arcan seems to be highly recommended. Am I better with a aluminum and steel jack, or all aluminum? Thanks in advance for your help. 1. Arcan HJ-3000 3-Ton Professional Grade Aluminum and Steel Hybrid Service Jack. This one sells for $249 from one Amazon seller because I think it's been discontinued. 2. Arcan ALJ3T 3-Ton Aluminum Floor Jack - $219 Amazon Prime with free shipping. It seems to get high recommendations from various online reviewers.
