at a reasonable price? I either see cameras that have been owned for years, or theres no telling what condition its in. They make look new because they've been babied, but I can't see the condition of the CCD or any of the inside mechanics. There is the route of going a NIB D100 for about 600, but I was planning on spending 600 total, as in body + lens. Are there any models out there with a similar feature layout of a D100 but is newer...D70 perhaps?
