camber kit question
 

i'm always toolin around with my civic.. i'm not plannin on doin any work until next summer but just wanted to start lookin around for suspension upgrades. I was lookin to full coilovers and nothing too crazy with wheels probably 16's. But i was looking at camber kits some people say they didn't do them others say you're nuts if you don't.. when looking i see prices from 35 on ebay up to 500 for the set. What's the deal with camber kits prices, brands and such?
