I have a pair of the Soliloquy SAT 5's that Jax2 recommends and they're my favorites of the many small speakers I've tried. I'm using them in a second system with the Onkyo 9555 I recommended in your other post and it's a wonderful combination. The Soliloquys will be hard to find, though maybe not any more so than the Spicas.
A current production speaker that's excellent for $400 retail is the Usher S-520. There's a Stereophile review online. I bought a pair for my daughter with a NAD all-in-one unit and it makes a great, simple setup.
For real budget speakers the Insignias that Goatwuss recommends are pretty amazing and another good option are the Athenas at about $100. I liked the previous generation of those better than some Paradigm Atoms I had.
