I have a Tahari suit that I got on sale at Macy's or Hecht's for about $120 or so. I forget how much they are regularly, but usually can find them on sale a lot. The only problem is you can't mix sizes, so the pants are a little weird and high waisted which I can't stand. But other than that, it looks good on.
I almost bought one from J Crew but would end being close to $400 and the suit was really heavy. Perfect for winter but not for spring/summer. Ebay might be a good option to get it cheaper, b/c they really fit well.
