Keep an eye on http://Slickdealz.net and watch for the different Dell deals. The guys there watch all the promotions and usually find some extraordinary deals. You'll notice that they don't have a high opinion of TigerDirect's rebate program, but it's still a solid site for pricing and deal research.
