When it comes to technology, there will ALWAYS be something better coming.
No matter what you buy, the next one will most likely be more powerful, have more features, and possibly be less expensive too. And if you wait, the one that follows that will be even better. So, do you want to wait forever or enjoy what's available while you're still around to use it?
I love my S50 but I may purchase an S30 or Dwarf 3 to get that wider field that satch984 mentioned.
