I went back to the computer shopper to look for other vendors and I checked out Gomez.com for information about computer/tech equipment vendors.  Computers4sure may be the vendor that I actually purchase from as their website is clean and reasonably easy to navigate.  In addition, they list the number of units that are in stock (I'm assuming that the numbers are accurate).  They received a high rating on Gomez.com and what Gomez says carries weight with me.  I am also investigating eCost.
