Yogiboy has a great recommendation with the Spendors. As he (and I) will tell you, the Harbeth P3s are a step up from the Spendors. However, they are both fantastic monitors, and the difference may be nothing more than personal preference. The Spendors have a soft dome tweeter. The Harbeths have a metal dome, but it's so well implemented that it's not bright and integrates perfectly with the mids.
The only thing that you might not like about the Spendor/Harbeth monitors is that they do lack some lower end. If you're used to tower speakers, the difference may be a bit much at first. However, I found that halfway through the first song with the Harbeths I was lost in the music and never noticed any lack of low end again.
There are some other good monitors listed here: Dynaudio Excite X12, for example.
Good luck!
