yeah aluminum jacks are the cats meow. i dont trust harbor freight tools to much due to their poor quality. and when the tools job is to hold a 2 ton car from falling and crushing you to death, i prefer higher quality. harbor freight is good for hammers and other stuff that wont hurt/kill you if it fails. most of the stuff i bought from them has failed eventually. and i have bought engine hoists, 3 nail guns, roto zips, grinders, water pumps, tile saws, wrenches, engine stands. etc. all three nail guns are broken, i had to get a new seal for the engine hoist, grinder died, and the wrenches broke. everything else still is working.
