I own and enjoy Silverline Minuets, they are $350 or so used probably. Mine are in a modest system and sound great.
I'd like to hear the Elac as well. They were selling some for $100 off due to a discolored cone defect but I'm not sure if there are amy left at that price.
The Peachtree are well thought of, too, and may be a great speaker.
I think you'll be able to get a nice pair of standmounts in your budget.
Good luck!
