I agree with the others that it is probably best to stick to one system. That said, my wife and I both have OM10s, along with OM2s and 4Tis and love them. They have been dropped, wet, covered in mud on archaeological digs etc, and both still work perfectly after tens of thousands of pictures over close to 20 years. They are a good introduction to the OM system for when you want to move up, and are still good second bodies once you have. They aren't worth getting without the separate manual shutter speed adaptor though, so make sure you can get one, otherwise, they are auto only.
