Get the Fuji S3 (new for $1,299.00 at KEH.com) instead of the Nikon D200 (new for $1,699.95 at KEH.com). The $400.00 extra you would spend for the D200 would mostly buy you (a) two fewer megapixels and (b) the word "NIKON" across the front instead of "FinePix." Nothing wrong with Nikon (still have my Nikkormat, Nikon F Photomic, motorized Nikon F3 HP, and autfocus N80), but for me the most digital "bang for your buck" is Fuji.
Most every review of Fuji DSLRs talk about the Fuji's superior rendering of skin tones, which, as a people photographer, is what led me to buy an S1, then an S2, and finally an S3 over all other available DSLRs. I can vouch for the excellent skin tones from all three of these cameras. In terms of resolution, my S3 compares very favorably to my 14 megapixel Kodak DCS Pro 14n. I used both regularly.
If you get an S3, use 512-megabyte or one-gigabyte Olympus Type H high-speed XD cards as your primary media. My tests show the XD Type H write time (and thereore your shooting speed) is 50% faster than the XD Type M, and the XD Type H is much faster than using any Compact Flash media, whether microdrive or not. The one-gigabyte XD card will give you 40 shots when shooting the S3 in RAW mode.
A used S2 in excellent condition at KEH.com is $645.00, almost half the price of a new S3, and the S2 is an excellent camera. However, there was a big problem with Fuji S2's about 1-1/2 years ago. I would avoid the S2 UNLESS you can be sure it either (a) has had the sensor replaced or (b) is NOT in the serial number range of the affected cameras. Fuji replaced S2's sensor for free back then; don't know wat is going on about that now.
