Schubeck lifters

Does anyone use these lifters? I have read alot of good stuff about them, but are they worth the price you have to pay for them? Heard they were reusable if you change the cam?

Just bought a new cam from hughes engines with 260/264 @50 lift with .587/594 " lift with 1.5 rockers.

Does anyone have them and what do you think of them?

Thx Chris
