a lot of people will recommend the rigid 4hp 5 gal model and i was goin to pick that up a while ago but they were out at home depot so i ran over to sears and found this craftsman http://www.sears.com/sr/javasr/product.do?BV_UseBVCookie=Yes&vertical=TOOL&pid=00917776000. when i did a detail at my dads house a few months ago, i found out he has the rigid. well i tried the rigid and the suction power compared to my craftsman wasnt as strong as my craftsman. the craftsman has a thinner hose and has more suction power. basically, i am much more happy with mine than the rigid and its actually easier to carry. if your looking for a great, very mobile, inexpensive, and amazing suction power vaccuum, this is the one for you
