I am it for small company (ie no money to buy tape backup solutions). I want a redundant, off-site solution.  Would the following satisfy this:

Using 2 external 500gb HD:

Do full backup everynight rotating the drives every day when I come in.  For example, I would bring in D2 Mon Morning and take home D1, the next day bring in D1, take home D2, etc.  Will this not assure that I always have atleast 1 day ago?

The solution that you proposed should work without any issues. I am currently using a solution similar to this for my work PC.

I would suggest you have a read over my backup comment - which grew into a backup web page.  

In short
I would probably suggest adding a 3rd hard drive to that rotation.  Your solution would PROBABLY be fine, but more information is really needed before you could be certain it's appropriate.  For example, how much data are you backing up?  Are there any regulatory requirements for keeping the backups over a long term or keeping them secure?  How fast is the data growing?

In detail, read the link:

the data is stable, and I have allowed for a 500% growth just in case.  There are no security issues, and no need for archiving daily backups.

Most external drives are going to Standard single drive enclosures.  However, ones larger than the maximum available drive size (currently 750GB as far as I've seen), will certainly be a RAID configuration.  It is POSSIBLE (though unlikely) that some of these units will be configured in a safer RAID 5 configuration.  Sometimes it's not easy to tell if the external drives are RAID 0 or not - look over the specs of the unit, ask sales people at the store, or call the manufacturer (possibly through a tech support line) and ask.
