My trusty 4-5 year old Fuji S1 has seen better days, so I've started searching around to see what's out there. That D3 is more than I would ever need. Must have Nikon mount for my existing lenses. It must be built like a tank because it will get
severely abused - that leaves out the pro-sumer D60, D70, whatevers. I'm thinking used/NOS Nikon D1x or D2h. The D1's 5.5MP is more than I normally shoot for business purposes and the all-metal body is as rugged as anything out there. $500 on eBay is a nice discount off the $5,500 MSRP too
D2h's seem to be going for $750-$1000. Much better high-speed capability, but that's not a priority for me.
Here's an interesting take on the sensor size dilemma. Count me as one who assumed bigger is better. Maybe not ....

EDIT: yeah, I'm with you on the uber megapixel cameras. I rarely shoot above 5 MP for business and these are for purposes of evidence in lawsuits. In fact, I'm usually complimented on how unbelievably clear the photos are.
