Dynaudio DM 2/10 (new). This is a stand mount speaker, but uses a 10" woofer and will put to shame most floorstanders.
Dynaudio Focus 140 (used). Again, a stand mount speaker, but sounds bigger than many floorstanders.
Monitor Audio RX6 or RX8 (new). These are both available around that price or less. They are both floorstanders and offer about the best bang for buck in that price range period. I prefer the RX6 which offers a nice high end sound but with plenty of full range bass as well. The RX8 bass needs a big room, but will serves up a knock out sound.
Totem Hawk (used). Rich full sound from a small floorstander.
B&W 684 (new) OR B&W CM7 (used) - The CM7 is a taste of the high end sound and a fantastic midrange. Very nice speaker.
All of these choices are dynamite and you can't really go wrong with any of them, but given your emphasis on "full-range" sound, I'd get the MA RX8.
