Just in time for the holiday season, SLR (single-lens reflex) digital cameras have reached a new low — in pricing. PC World reports that Canon’s EOS Digital Rebel is the first SLR priced below $1000. The 6.3-megapixel unit is $899 (body only); for $100 more you can add Canon’s EF-S 18mm-to-55mm lens, which makes the Rebel cost about $600 less than its closest competitors.
