I bought my D70s kit from Bestbuy for 799 and I love it. Found the 18-200 VR for $719 and will sell the 18-70 lens next week. Love having the Best Buy warranty for the body and the Nikon warranty for the lenses.
Save your money, it's worth it. I sold my used books on Amazon.com for about 2 months and made over $700 towards my purchase.
$799 for the Nikon D70s is very cheap indeed! In my country, it is still selling for around $1000. (With the 18 - 70 mm E.D. lens)
