Adjustable back & seat creeper

[mikebike]

I'm looking to get a creeper with both an adjustable (inclined) back & seat. These look like the same item, branded differently:

I'm just checking to see if anyone out here knows of a better (read: cheaper) source for this, or comparable, creeper.

Thanks!
