Looking to update my crossovers. Active or Passive

Well here's what I have right now i'm using a set of passive Eminance 3 ways from "partsexpress.com" And yes I am a victim of the upgrade bug. I'm upgrading my tweeters and thought I'd try to get some info on a new set of crossovers as well. My speakers are Homemade 3-ways(using a modified design from speakerbuilder mag), single amp powering them, and tri-wiring from the crossovers to the speakers. I haven't been able to find to many places that sell crossovers especially active ones so what do you think?? Active or Passive? Also where can I get some good ones??
