Can anyone suggest a GOOD creeper! There seems to be a billion types that all claim to be good but who knows until you actually buy one and use it. I've had 2 pieces of crap that I'm so disgusted with I'm ready to toss them in the garbage. Wheels don't stay tight and don't last long and will barely roll over a small pebble. One has a head rest that'd be great if it would stay up. Having it drop like a rock unexpectedly when your in the middle of working is a real pain (no pun intended). I'd like one with a good head rest that raises up (and stays up when it's supposed to). Side racks for tools etc. are ok but if that drives up the price a lot forget it. I have a nice concrete garage floor so I don't need huge 6" wheels, just decent lasting and properly attached wheels. I've got $150 to spend on one. I'd think that should get me something decent.
