It also depends where you're going to use the GPS. If you want to use the IPAQ outside your local bit of the UK or in Europe, then memorymap software or Jepp digital maps are going to set you back a fair whack. Even if you use donation programs like PocketFMS, you are still going to have to upload the right bits of map into the IPAQ which could be a pain. The 196 has all of Europe already loaded (and further afield too). That's what clinched it for me.
