That's the one: Electrum. I followed (I think!) the recommendations and went with that one.
Hey dudley, good choice. Always remember that you should check the version of the one that you're using because the older versions are vulnerable and can be penetrated by hackers/phishers.
The reminder is on the official Electrum website at the top of it. Just for you to avoid what others have experienced. It's a very simple reminder but it will save you from trouble if you're aware of it.
