I need your help guys..

I plan on finally lowering my car on firday but I still can't decided b/w the sportlines or Tein. Here's my dilema, from reading past forums it appears these two springs have relatively the same drop (1.5") but the tein are much cheaper in price which comes in handy when I have to buy my camber kit. Secondly, I hear stories that the sportlines have an unequal drop where at times the rear is lower than the front and sometimes vice versa. But I can't get forget about the Eibach name where I know I'll will be getting my moneys worth, yet at the same time I dont want to pay so much knowing I can get the same quality and drop and a fraction of the cost. What should I do? People with the sportlines and Teins, I need your help:(
