Chan Tran's sure right about the F5. It's amazing to me how much its price has fallen. Canon's equivalent, which I'm thinking is the EOS 1n RS, seems to be going for about the same price. Just amazing. Meanwhile, clean examples of old classics like the Original Canon F-1 and Nikon F2 seem to be increasing in value. Probably the best values in AF Nikon and Canon, in terms of the amount of features you get for the price, I believe are the Canon EOS 3 and the Nikon F100. Both fantastic cameras at almost sinfully low prices.
+1 on the quietness of the EOS Elan. I own a II and a IIe, and the drives really are quiet. Great prices on these cameras too. I paid like $250 for my Elan IIe with 28-80 zoom about five years ago, and the camera body now goes on eBay for what? $30? $40? Unbelievable.
