Placement of Cisco Secure IDS Sensor

I have a site that is using a Cisco PIX firewall, and it has three interfaces: inside, outside and a DMZ. I only have funding for one Cisco Secure IDS Sensor. Where do you recommend I put it?
If I could only have one sensor, I would put it on the outside, before my firewall. That way the IDS could potentially catch attacks against my firewall, as well as other attacks. However, I would argue for a larger budget to procure a few more sensors.
