I'm in the market for a pair of stand-mounted bookshelf speakers. I plan to buy used to get the best value I can. I've been looking on ebay and have found the following:

Paradigm Titan v2 or later
Paradigm Atoms v2 or later
Paradigm Mini Monitor v2 or later

Mission 700 series
NHT Classic 3
Aurum Cantus 2 SE
Dunlavy SC1
Emotiva ERM-1

I'm open to other choices as well. I haven't heard all the Paradigms, so would appreciate recommendations on which is better for 2-channel listening. I don't really want to spend over $400, but will consider choices up to $450. I look forward to discussing your recommendations.
