I own an EOS 500, which is very small and light - In fact, so light as on first inspection to seem cheap and slightly flimsy. This is an illusion, as it has stood up well to the heavy use I have given it. There are only a couple of things I don't like about it - The plastic lens mount (although it has never actually been a problem), and the design of the pop up flash. The flash has a small lip that sticks out very slightly, and on a number of occasions I have caught this and yanked the flash up. While this hasn't caused any damage, it can't be good for the camera. It's worth noting that the EOS 5 also has the same design of flash.
A friend has an EOS 50E, which I really like. It seems well built, and it has a rear command dial as well as the front one.
I like the look of the 30 & 33v, and I have used the 33V briefly. they seem generally good cameras.
A while ago, I had an accident with my other EOS 500. I won't go into the sordid details, but basically I put my finger through the shutter curtain

Thus I went camera hunting, and found an EOS 1N. After thinking for about 2.5 nanoseconds, I bought it.
The 1N suits me perfectly. As a camera, it is very fast and responsive, and the design is great. The build quality is extremely high, and the grip fits my hand as if it were custom made.
One feature I haven't used myself, but others might, is the silent wind. This slows the wind & rewind speed down, so it becomes very quiet.
It is also completely safe with all types of IR film, using a mechanical rather than an infrared counter.
I'm still trying to find an excuse to run HIE through it at 6 FPS...
