The rockit's were my first set because of all the great reviews 4-5 years ago, they were a good starter set if your strapped for cash but they hiss like a mofo distorting a lot of what your hearing so you'd be better off saving a little more. The Yamaha's are much better I've herd the hs80's, they are nice, lots of used sets on the net for cheap.
currently have the jbl lsr4326 and love them. I know the jbl lsr2326's are cheap price wise but have not listened to them but they could be another option.
