Life span of Eibach and H&R springs

[pejohnson]

Seeing a few of these popping up used, just wondering how long and how many miles H&R and Eibach springs are good for?  On Eibach's website they have the 'million mile warranty'.  I would assume same quality from H&R.   I think OEM generally last between 50k and 70k understanding mileage can vary depending on driving conditions.  Thinking of maybe buying a used set and want to make sure I buy a set that isn't already worn out.  I like the idea of buying a set that is already broken in.  Thoughts?

Eibachs have a million mile warranty lol
H&R is at very least just as good a product.

Springs? 

Man I never thought about it, but I'd say at least 200k. 

Shocks, not so much.

I know on the Gen I and II SHO's they had the saggy a$$ syndrome and the rear OEM springs needed replaced frequently.  I am assuming the aftermarket springs are far superior and will last much longer.
