Swan has several good ones. If you're looking at any of the under $300 (a pair) range I'd suggest one of the trio (L/R sub) sets - very good sound at the price point.
Re more professional grade - in the edit/mixing bays where I've worked Adam Audio near field monitors (some AX5s, mostly AX7's or AX8's) are a favorite, but I think they are more in the $700-$1000 range.
Genelec used to be a favorite in edit/mixing bays - they sounded great but many thought the under 1K series weren't "neutral" enough for reference work. I mention them because currently it's easy to find them for sale used, and the "neutral" thing wouldn't apply to home use (unless you're mixing music), they would be excellent speakers for the money.
(Note - the edit/mixing bays I'm referring to are offline bays, not finishing bays. Finishing bays is a whole other, very expensive, world.)
