ah hia, pls don't give make him faint leh. the price will give him a shock...
try out other rides with different aftermarket shocks.
if you only want it lower, just change the springs. H&R is the most popular.
if you want to improve handling, then change the dampers as well. there are quite a few out there - koni and k&w are the most popular.
if you want to go to the max, there are coilovers. you can adjust height, damping, camber (but only with pillow ball mounts)... but only if you really want to go to the extreme, cos they are not cheap.
and there's also the wifey factor, some of them do not like to sacrifice the comfort.
