Nice, clean looking sites. I would list 'em.
I would make sure that removing the PI recip link won't get you blacklisted. I know they've changed the deal on that, but it's good joss to check with em, especially if they already gave you a better listing base on it.
btw, there's something funky going on with your sites in Nutscrape. Images are loading over text. At least that's what I'm seeing. That's usually something in the css, like conflicting line heights.
