the d70 is a very nice camera - very compact for a dslr. If you pick up a digital rebel, then pick up the nikon, i guarentee you'll buy the nikon. The rebel is cheaper buy several hundred dollars, but it's plastic! canon's 10d is a little less expensive on ebay because it was released earlier than the d70. They can be had for less than $900.00. Belive me - i bought my 10d off ebay for 850 bucks - less than 6 months old and less than 1000 shots on it. A few months ago - you couldn't even buy a d70 - you were put on a waiting list.
There are alot of deals to be had if you don't mind buying used. If you plan on buying new - espesially a dslr - most pro camera stores offer a 30 day exchange policy, allowing you to upgrade or downgrade - no problems. Good luck shopping, and compare prices.
Also if you need memory cards - right now at costco 512mb cards are only $64.99 - $10.00 instant rebate. crazy!
