$800 for coilovers and shocks new, can be found used for $500-600 but pretty rare although the koni yellows can be rebuilt if you find a good enough deal
$200 should get strut tower bar, front camber kit, rear washer trick for camber, and maybe some other odds and ends if you find deals
its at least a start, but yes more money would be better, suspension work is a slippery slope, there is always a weakest link and something to upgrade
