We have a Nikon D90 that we absolutely love.

DH will be going out of town and needs the camera at the same time I will go on a trip with the kids. I need a camera for my trip.

At first I was thinking of getting a cheap point and shoot so I could keep it in my purse later for handy snaps of the kids etc. (meaning the camera wouldn't be just for the trip)

But I know the photo quality will be nowhere close to what I'm used to with the D90 and having good pics from this trip is important to me.

Then I thought of picking up a used D90 on eBay. I could use it for my purposes and turn around and resell it - hopefully for about what I paid.

Do you camera people have any other model suggestions? I'm used to the D90 and I trust it for good quality pics so that's why I thought of that one. But I haven't kept up with Nikon's model changes since we bought ours in 2010.

When buying used I know to look for number of shutter clicks and general (overall) condition. And what kind of range is ok vs not? Anything else to look out for?

I will be shooting vaca snapshots so I don't think I need any special lenses. I can get by on a normal one (forgot the specs now). Depending on what I find on ebay, I could keep whatever we wanted and sell the rest so long as it is compatible with our existing D90.

Thoughts? Ideas? Suggestions?

Thanks in advance.
