What would the experts recommend for a good packet analyzer /sniffer these days? I have a good network background but am not interested in wading through very low level network traffic to figure out everything by myself, and want to find a software package that has some decent analysis of the packets. I support a variety of different networks, so it can't be hardware centric (switch or router). The product should probably be Windows-based for my laptop, it doesn't have to be freeware or shareware but it needs to be under $1,000. Please consider price with the features when analyzing. Links appreciated.
