This post was made for USCF and CFC, most of the events in NA are not fide rated but nationally rated.

I looked it up and there is a Fide approved leap clock on Amazon for 27 USD, but the price point is probably different if you're living in Europe.

The leap clock I have does have all the features you mentioned except sudden death. I'm assuming this fide one has sudden death on it.
