I was considering a 2.0l bottom end for mine but I had a long think and thought i'd be safer rebuilding my own. The cost of a rebuild compared to gettin another block isn't much different if you know the right people. I would hate to buy a bottom end, fit it, use for it for a few hundred miles and then the the thing go boom. As i'm re-building mine I will know exactly what condition its in and know it should affectively be a 0 mile engine, peace of mind to the max

But thats only me, others may disagree.
