I can recommend the cheapy kits on ebay... I have one fitted to my valver at present.
depends on what you want, they only lower the car, I don't think the handling improves a great deal, but you do get e decent ride, not too hard and bumpy.
I'm looking to upgrade in the near future (and also lift the height a taj running at -80mm which is a bit too low really for a daily driver!), would really like eibach/koni, but need to save hard for that combo!
