Well, coilovers are not cheap, lol.

A good set of coilovers from Tein will run you about $1200-$1600 brand new though I've seen a set go for as low as $900 used. I'll be buying new, though. I don't really trust a used set of shocks or coilovers as I don't know if the guy is giving me all the special adjustment/alignment tools or if they've been abused. I haven't priced any of the other brands, though. With a hookup, you should be able to get a set of Tein Flex which is an excellent street comfort set of coilovers for around $1250-ish (retail is $1430). I was thinking of getting a set of Tein RA but they're a bit pricey at $1650. I'll see if/when I wear out my stock suspension.
