Another 2,000 Speaker Question

First off, let me say that I am not an audiophile, but a music lover (which means I need help!). I would like to start building my system by replacing the (mostly junk) I have currently with a quality system. Unfortunately, I am also not near a good high end dealer. The listening room is rectangular, but the speakers would fire across, not down, the room. I listen to blues, rock, acoustic music, some jazz, but little classical. I recently read a review in Stereophile regarding the Magnepan 3.6 speakers; while those are out of my price range, I often see the 3.5's used for about 2,000 or so. What are your thoughts regarding the 3.5's vs. the 1.6 Magnepans? I currently have a McIntosh amp, which will eventually have to be replaced (sooner rather than later if I go with the Maggies due to their power requirements) Does anyone have any thoughts regarding non-electrostatics in this price range, such as the PSB GOlds or Paradigm 100's? Also, have you had success with used components and their value vs. brand new product lines? Any help is appreciated.
