Looking for a decent creeper

I've been lookin for a decent creeper since 1974. There are none, because layin on the ground is no fun. The "best" one I've found is a Snap On creeper I got probably about 1989 or so. The wheels have a lifetime warranty. Blew me away. My Snap On dealer came out to my house and replaced them free. Even still, it's an uncomfortable **** at times.
