Silverline Minuet, Elac UB5, and if you are willing to go just a bit over budget, the KEF LS-5o is among the best around at any price in a small room.(That is what I use in my 9x11 room with great results) Any of these could be driven to good effect with modest, but carefully picked out electronics. As you know, when you are assembling a world class playback system at any budget, make sure to select the best source components you can afford.

Best small used monitors under $1000
What what speakers and associated equipment integrated, cables etc. Small room approx 10x12. What speakers make you want to listen for hours and forget about the equipment or the endless search.
