Okay- the original poster wanted a camera that was easier to use than an N90. Prices on the N90 are way down- looks like $40 will pick up one at KEH. Last year, I bought an F3HP from them for $90 in BGN condition. All great cameras at dirt-cheap prices.
But I would not suggest an F100, N90, or F3HP as being easier to use than an N90. I think a camera with auto-everything and built in flash is closer to the mark. Add in "low-price", an N70 is worth considering. If the F80 can be bought at about the same price of under $50, look at it as well. Otherwise it is just going to be auto-everything for more money.
If someone wanted THE top notch Nikon, I would suggest the Nikon SP. If they wanted THE top notch Nikon SLR, a Black F2AS with an F1.2 lens is the one that I grab. But they do not fit in here, so I will not.
