Craftsman makes an aluminum one that is just awesome. It is low profile and so light you can move it with ease and place it anywhere with one hand/arm. Only downside is price, I forget how much my dad paid for it but he told me it cost about 3 times what we paid for our regular bulky steel...
Was really sad when my parents sold our 94' Thunderbird. Me and my dad did a lot of wrenching on it and also it was my first car in high school. They sold it to my friend who ended up totaling it within a month of buying it. :cry:
