the ground controls are about $1600, the apexi and tanabe are both around $1400. a slew of companies are bringing out full coilover setups now, such as ground control, 5zigen, HP Motorsports, Vis, konig, intrax, sprint, and several other spring companies, but theyre all around the same price, with the exception of the ricky racer Lo-Boyz, which are only $600. one of the recent issues of super street did a comparison of some of those companies, so you could check there for all the info but i dont know which issue i saw it in. http://www.geocities.com/blue2gnt
