Ebay's springs VS branded?

[AyashiFX55]

Hi guys, i have a celica GT 2000 , the suspensions are still stiff but i want it to be lowered. I asked few sellers here to buy their tein's or ksport's , just waiting for their responses.....mean while, i was wondering what's the difference between ebay's non-branded springs VS branded springs?? I won't track. Thank you for your advices , im just curious what determines the costs of the springs.....

basically, you get what you pay for. low price springs = low quality ride. it'll probably be bouncy.
