To be honest, there are only two places worth to submit - LOR and PB. When I submit my free site, I also add some link lists that are still active (mostly operated by people from this board). Few months ago I used almost 20 recips, now it's about 10-14 - it doesn't hurt as I have a better control over the process and the traffic is +/- on the same level.
All in all, free site submitting is still worth the time for me.
