Where can I find the best deals for the FAL electric fan

[BigVinnie]

I've been searching around for an electric fan assembly for my 91 s13....
I'm a bit confused about the descriptions.
First I was looking into getting the FAL 345 which comes with the mounting brackets, but not shure if it comes with the thermostatic switch, and wires needed with assembly (assuming that it does since the price for it is around $300 with brackets).
Then I looked into the FAL210/220 dual 12" that doesn't come with bracket hardware, and the 210 only comes with the thermostatic switch.
Also whats the different CFM rating's between the 2 everytime I look at the descriptions the 210/220 has 2500CFM, and at looking at the 345 it isn't very direct, but I am assuming 2200CFM.
Which one is better for the price and which one will come with all the parts needed including the thermostatic switch for a quick install. What is the best store to buy from online as well.
