Small Speakers 4 a Small System w/ Advent Receiver

Hi All. I just purchased a well maintained Advent 300 receiver, and I want to use it to make a nice, little, mini, inexpensive office system. So I'm looking for a set of small speakers (<5" woofers) to sit on my desk on either side of the monitor, that I can listen to in the near field, that work well with the Advent (15wpc). One poster suggested stearing clear of metal tweeters with this receiver - but that's just one person's opinion. I don't want to pay more than $100 or so (used or new). C'mon - put your thinking caps on! Any suggestions? Paradigm Micros?
