A decent point & shoot can be had for $200 or less these days that will excel at this type of photography. You certainly don't need a DSLR for 'product' type shots like these as the subject (for the most part) is static. As long as the light's good, you'll be fine.
With that said, if photography is a hobby or you tend toward the 'enthusiast', the high end P&S (Canon G series) or entry level DSLR's (aforementioned Canon Rebel or Nikon D3100 or D5100) are very affordable these days. Just remember, with a DSLR, the body is only half the equation (and the inexpensive part). It's the lenses (and your ability) that make the difference.
