I love my Nikons. The F3 is a lot of camera, but it's a bit bigger than the FE and as someone already pointed out, it needs an adapter if you want to mount a flash (other than a SB- with the right type base).
If you are sensitive to size, you may want an FE, but I love my F3. They usually go for around $120 but keep an eye on KEH -- price varies and BGN grade can be a great deal if you're not concerned with cosmetics.
