All aluminum floor jack. Arcan's 3 ton steel version had good reviews and I own 1 of them. I was at Costco this weekend and noticed that they had a new jack on the floor. It was their all aluminum model. While their all aluminum model has not had any reviews as of yet. It is fairly cheap at 139 - Northern Tool sells the 2 ton version for 210 with shipping. I was planning on buying one so I'll let you all know how it handles after.
