Best IIS gzip compression?

So it took me too long, but I just realized that IIS6 does not uses gzip compression by default. IIS6 ships with gzip compression capabilities, but they're turned off by default, and moreover, not straight forward to turn on. You can turn them on for application/dynamic files and static files... the static ones are rather simple, but for the dynamic you need to specify the extensions either through scripting or editing the metabase.xml.

Nevertheless, guess what, couldn't get cfm/cfc files to compress ... well, haven't spent more than 10 minutes, but it shouldn't really take more than that. After these 10 minutes I remembered that there's software out there to tweak and ease up configuring the IIS settings. The most popular one is port80's httpZip, and there's also pipeBoost. After after reading Microsoft's instructions and looking at the two commercial products, which one would you recommend? Have you guys have any experience with either and ColdFusion servers?
