Wheel of Fortune or just Creepy Crap?

My son found this bug outside our front door.  Turns out it's a young Wheel Bug or Assassin Bug... very creepy.  I've never seen anything like this before.  It's very agressive and supposedly has a nasty bite to it (Hubby got bit last night, so I'm wondering if this is the culprit) but is also very good for gardens as they eat any bug that they can overpower.  Scary.  Now I'm itchy all over.

I found some information on it at the following:

I'm a bit disturbed that there is an actual site named "AssassinBug.com" but I'm not one for bugs.  But I'm disturbed that there's a bug like this out there too.  Check out this video and tell me that this isn't a creepy bug!  http://youtu.be/xmV6TjVNZGM

Here's another shot of the one outside our house.

So, we've started planting all sorts of flowers and veggies outside.  It's a good bug to have to keep the garden bugs down, but it's an aggressive bug and I'm not in the mood to make a trip to the ER on a chance encounter.  What are your thoughts?  Wheel Bug of Fortune for my garden?  Or Creepy Crawly on the Crush-List?
