i wouldn't be able to pass up on good deals.. i'd go with the bottom end unless you feel you can pick another one up (or something comparable) in the future.

I was in the same boat and I found some BNIB eibach 2" lower springs on ebay for 30+shipping so it solved my ride-height problem for now. If i want i can revalve the stock Bilsteins but they are holding for now.
