Pretty much you get what you pay for. More bang for the buck I guess.
Nuespeed if your on a low budget.
H&R, Eibach, Omni.
If you want a less bouncy ride get lowering springs.
Coilovers are cool cuz you can adjust ride height but alot of them are bouncy unless you get something that is matched for ex
Omni coilover kit
Skunk2 coilover kit
Koni yellow with Ground Control (not matched but they r good together)
Ksport coilover kit
Coilovers:
Get something matched or ride is gonna be more bouncy
Springs:
Pretty much H&R, Skunk2, Eibach, or Nuespeed are whats good for an affordable price.
