02 cavalier coil-on-plug ????

Does anyone know how much the coil-on-plug setup is for a 02 Cavalier w/ the 2.2L Ecotec engine is? It's not available at any autoparts stores and I would just like to know. I found a kit by Nology that converts it to a normal coil and plug wire setup that cost $260. Are there any other options besides just replacing with original equipment? Thanks.
