MOTM

In anticipation of my 650 arriving, I'm looking to add a 5V supply.  
I'm assuming a linear supply would be preferable, but with all the  
cheap 5V wall wart switching supplies floating around, could I use  
one of those without causing myself too much trouble? I'd be hooking  
it up to the terminals on my 990 distribution board for 5V and its  
associated ground.

There are some cheapish 5V linear regulated wall warts at Jameco -  
what about those?
