We use this little shop vac at work to clean electronics - http://www.lowes.com/pd_215726-20097...28&CAGPSPN=pla - and I ended up buying one for my own use, has plenty of suction and the blower function is pretty nice. They also sell a "Shop-Vac Micro Cleaning Kit" with a bunch of small nozzles and extensions including ones with brushes on the end.

FWIW, haven't had issues with the extension, it's got a bit of give for stretch and the vacuum itself is fairly mobile inside the car. You'll need a nice extension chord for the outlet though.

gets the job done

I heard that one really sucks.

really ? it sucks everything, haha I have no problems

Yeah I've heard the battery is pretty weak.

I just picked up a Stanley 5 gal 4.5hp from Amazon for $44.

If you want a great vac for around $100 look up the Metro Vac N Blo.

Ah yea sorry bad joke! In all seriousness it gets solid reviews on Amazon and i've been quite happy with my Dyson vac here as well.

We have a fullsize Dyson at home, it's better than any shop vacuum I've owned before. Though it doesn't have such a large pipe diameter as a shop vac for big pieces, or able to take up water. It's really good. And you can even use it in the house without your wife yelling at you.
