Realistically, how often do you think you'll adjust them? From my experience, if it's a daily, you'll tinker with them till you get the height where you want it and leave it there. It gets somewhat tiresome pulling all the wheels off to change the height for the weekend or whatever and you should also be getting a wheel alignment every time you change the height.
The right height can easily be achieved with the right spring and you will get a better ride with good quality shocks as well as likely come out with change in your pocket compared to a cheap coilover set...that can then go towards sway bars
If you're set on coilovers, go with a good set like kw or the like. Personally I've got nothing nice to say about the Pedders ones and can only imagine XYZ and all the other cheap sets are the same.
