To buy or not to buy? klf's, sub, and center

[BigLoad76]

On the local craigs, i stumbled across these. I am not really interested in the receiver, or the nht's but the klipsch is a diferent story (thants why we are all here). I have not seen any of them yet so i dont know the condition. I also have a fair setup already, but i was curious as to how the klf's would sound as mains over my rf35's or even possibly surrounds over the rs42's. I need a sub, so the ksw will sound great for now. And i could always use a space center. I emailed him and He told me 160 for the all the klipsch. Sounds like a decent set for the price but i am unfamiliar with most of the equip. Below is a copy/paste from the post. with arrows pointing to what i am interested in.
