$45 on Amazon. Not cheap, but not expensive.

Pros:

High volume rates                            (in case I pop a bead)
Low amperage                                 (who needs a blown fuse! >10amps)
Big scale increments at low pressure. (better accuracy at low pressure)
Press clip chuck                                (less leakage on disconnect)
Doesn't overheat                              (no cooling period after use)
Steel protective case.                       (Bouncing around on the Z)                             

Cons:

It's bigger than I'd like.    (9.5x9.5x4.5)
No reliable review history (But VIAIR has a good reputation)

I wonder what I've missed.

Shoot I think mine puts out less then 1cfm so already this one is on top in my book.

For those interested in a drop-dead reliable small form factor pump, I ran across the MotoPumps website. 

The MiniPro is a well engineered and manufactured product with a 5 year warranty and lots of happy customers. It can fit in your pocket, weighs a shade over a pound, provides good volume (.5cfm) for its size and low amps (<5), and is continuous use like the Viair. 

The cord is a little short (6.5') and it's a little pricey ($70).

It didn't satisfy my volume requirements, but it's more than a lot of other bigger compressors, so it  might be perfect for others here.

I have a pump https://www.amazon.com/gp/product/B01H6GQJHS/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1
It is very small. I have had to use it one time when I put a huge hole in my 29" rear tire. I plugged the tire and it did fill up the tire, it took about 20 minutes though with a few minute break after 5 minutes so it wouldn't overheat. So for cheap money and for very small, it works. It is for emergency only though I wouldn't use it every day. I a real compressor in my garage for the cars toys and bikes for pressure checks and adjustments.

I removed my post that said the Viair 75P didn't fit in the front storage box. In fact, it fits pretty well

It's bigger than I hoped, but it's still a keeper. All the other tire bits are underneath it along with other items.
