It's interesting, but not surprising, that so many of these recommendations are meant to steer you toward the purchase of either a Canon or Nikon DSLR, even if that recommendation would put you out of your stated price range. There have been few mentions of Pentax, and one of those was from a poster who somehow views Pentax's aborted merger with a lens filter manufacturer as a reason to avoid their products.
The fact is that Pentax provides a model which is specifically targeted for those of us in the market for an entry level DSLR: the 6 Megapixel K100D/K110D. I opted for the K110D which is identical to the K100D save the absence of the Petnax Shake Reduction technology. Price with the 15-55mm f4-5.6 kit lens was $400.00; $350.00 after Pentax rebate which has been extended to May 31. Buy another of Pentax's current model lenses and get another $50.00 rebate.
Why no one else has made this recommendation is a puzzle, but I suspect that most people just default to Canon and Nikon, or perhaps have a pointed anti-Pentax bias. Is the K100D any good? I'd say so, but don't take my word for it:

Also, I recommend that you actually physically handle and evaluate it with specific attention to the build quality; something I suspect most buyers don't do. Compare the K100D to the already recommended, and considerably more expensive models from Nikon and Canon. You might be surprised by that comparison.
Good Luck.
