Might be a bit of a challenge...

The Disto X2 module was discontinued some time ago and there have been various discussions on alternatives, see:

However I've got a vague memory of someone saying recently that they were getting made again, but I can't recall who said it, or where... Perhaps someone else knows 

The X310 has also been discontinued by Leica and they're now pretty thin on the ground. The price on eBay has doubled in the past 12 months.

I suspect its the final nail in the coffin for the Distox2 - I'm glad I managed to sell all of the batteries I had!
