The Morel Lifter I run is in the $350 dollar range, they do have a higher end lifter that is rebuildable and has a extra oil hole on top of the lifter. From what I've seen the cheaper ones last longer.
A lot of stuff from comp is built 10 mins from me, trying to cut corners to save a few bucks really has a long term affect on a lifter is why you seen them go down hill.
