Air Compressor options

I am going to buy an air compressor this summer for under $200 and need some info. I will also be calling Hornblaster and Viair as well.

I want a compressor that can be used to fill tires and be used for a locker in the future. If I go portable I cannot use it for the lockers but the compressor can stay out the way and pay a little less (sell the portable once I get a mounted unit.) If I get a mounted compressor how would I mount it to keep it dry and clean? The price of a good mounted compressor is a con for me. Is it worth it to have a high CFM portable?

Staying under $200, here is what I am looking at so far (leaning towards the 400p):

Mounted:

We are a VIAIR dealer.

 

I knew that (forgot). I should call you guys as well! I also know you have co2 systems but I dont think they fit my application.

 

Probably just need a medium sized on-board kit.

 

Yea but then I will be over $200 and I can't really do that right now (I think I will put that in the original post). Do you have a pre assembled kit? PM me if you want.

Is it ok to run the 400c as direct fill?
