I'm sure the needswings catch can is great, but it's $140 (not 180, sorry) and I really like the idea of having a clear container to see all the gunk so you know when to empty it.
I guess I'll have to do a search here and see what everyone else has done. Thanks for the heads up, woody!
EDIT: Looks like quite a few people went with this one:

Looks like that would fit my budget and has the clear catch so I can see it. I'd be interested to see some feedback for those who have this setup. Woody?
