They have a
dealer list on their web site.
If my link doesn't work to get you there directly, go to their
front page and navigate your way to it.
I don't see anyone in Columbus.
Maybe you can see someone close enough.
I recognize several names on the list as being seriously aggressive in their pricing.
As always, beware of shipping and handling fees, if you decide to order by phone/web site.
While you are looking, did you read the
favorable review we have here of the Visionsat IV 200?
Pretty much similar box, but I think you'll find its market price is around $50 less.
Seems to be getting good factory support, too.
