Prological:
Biggish room, weakish equipment (but it's good enough for now, given your plans). I know them solely by reputation, but people I know know what they're talking about highly recommend NewForm Research R630. Brand spankin' new they're at the top of your price range, used they're available at the bottom. Hybrid ribbons with ScanSpeak mid drivers, specs that compare well with all the monitors you mention, and (I'm told) very musical. Plus, they would obviate the need for(and additional expense of) stands. Plus, they should be up for whatever you get for your next upgrade (not that any of your selected monitors wouldn't, mind you!). Unless you specifically need monitors for a reason (and room size clearly isn't one) then this would be my recommendation.
If I still get a vote, and you are intent on buying by popular demand, then I go with the Silverlines (but then, I own 'em!)
