Metro Vacuum Master Blaster Dryers

Zipper 104

I know a number of you here have some of these Air Blasters.
I am thinking of getting one and naturally due to it's small size I would prefer the small Side Kick model. Before I do I want to make sure the volume of air output would be adequate on a car before I lay out the $$$ only to find out it isn't and I've wasted the money.
I know they make at least two larger models and both would probably be plenty powerful enough, but I don't want to be dragging them out to where I wash my car everytime, hence the Side Kick.
Anyone here have experience with a Side Kick to be able to comment on whether it is up to the job or not?
I've seen videos of the Side Kicks on You Tube and I don't really think they're powerful enough but I'd like to see if anyone here has had first hand experience with one and can comment on one.
I didn't post a link up to a website since those of you with one one of these rigs know what I'm referring to.

Thanks in advance.
