Yeh, which is why i said save up.
I got lucky, my eibach dampers were £120 for the set of four (clearance stock on ebay!), and the springs were ~£150.
Also different folk have different ideas of what constitutes a comfortable ride, and whats appropriate for their use.
My biggest issue is that cheap coilovers are usually designed to allow folk to slam a car on its ring (because otherwise you'd have baught a £300 -40mm suspension kit instead). If you slam a car, you need extremely stiff springs, because you've limited suspension travel and dont want the suspension bottoming out.
And contrary to popular belief, a stiff car that "handles like its on rails" will often have less actual grip than another car on properly designed suspension, because your suspension needs to deal with real roads which have bumps and potholes and rough bits. Proper suspension will absorb the bumps and keep the wheels touching the road. Stiff suspension will allow the car to skip and bounce over these road features, resulting in a car whose wheels arent actually touching the ground.
It may well be that the FK's are soft enough to give a good ride, but that softness directly means you wont be able to run them low without hitting the bump stops, and hitting the bump stops is even worse than having stiff springs.
