Bridging as sniffing method?

Hi, I'm currently looking at sampling network traffic using snort and ethereal. My problem is that the network in question is predominantly switched ethernet. I have considered a number of switched network sniffing methods: 1. Configuring a span ports on selected switches. 2. Purchase an aggregating network tap. 3. Use ARP poisoning to redirect and route traffic through my lappy. 4. Setup my pentest laptop as a network bridge. Of these, I'm inclined to go with span ports or the network tap as the best solution. However, bridging intrigues me. Has anyone on the list had any experience (good or bad) with establishing a bridge to sniff switched LAN traffic? I've tested out a working config using FreeBSD with two NICs and it appears to work OK, but I'm not confident of the robustness or integrity of the bridge - any advice would be most appreciated...
