Fleabay.... they don't seem like a bad deal if they are actually any good.

as long as they are 12V Pullers they should be fine.

NC, before you buy them, ask if they are 1840 cfm each, or is that a total CFM pull. You are wanting atleast 3,000 cfm with the fans running. Less than that and you can have issues with overheating when it stop and go traffic.

Now you will just need a good controller (or two) for them. Stay away from the wire wound controllers. They are cheap, but you are getting what you are paying for. They work great for the first year or so, but then require a lot of attention to keep things working.
