It's not easy to find many digital SLRs with a lens kit of some sort for under $500. But digital SLRs have increased in terms of affordability, and they can be put in a gift guide for the avid traveler - I just got my first digital SLR and like the results I am seeing.
1. Olympus Evolt E-420 Black SLR Digital Camera Kit
Several retailers sell this camera for under $500.
2. Canon EOS 350D Digital Rebel XT Digital SLR Camera Kit w/ 18-55mm Lens - Silver
This Canon series is popular with the digital SLR set. 8.0 mp and a lens included, and is very reasonably priced for a digital SLR - several online merchants I saw were selling this for less than $250!3. Nikon D40 SLR Digital Camera Kit
This Nikon has a lower megapixel count of 6.1 and is often seen as an entry level digital SLR around the $400-$450 mark.4. Pentax K10D SLR Digital Camera
This Pentax digital SLR features 10.2 effective megapixels and comes with an 18-55mm lens.5. Sony alpha DSLR-A200K SLR Digital Camera Kit with 18-70mm Lens
Priced around the $450 - $500 range, Sony Alphas seem to be a popular entry level digital SLR as well.6. Canon EOS Rebel XS Black SLR Digital Camera Kit
This Canon camera kit is around the $450 mark and a newer model (with 10.1 MP) than the one I mentioned earlier that was half this camera's price.
