does anyone have a cloned site that works for the estimator?
No on will have a cloned site as at the moment Bitcontalk.org is blocking bots from accessing the information needed which means this piece of code will not work until that's either whitelisted for this site or whitelisted globally.
Forgive my lack of intelligence if I may sound stupid but you can always programmatically browse a website just like you would do with an actual user and bitcontalk wouldn't see it as a spam bot unless you're opening multiple threads/spamming.

You can follow the OP's github page and run a local clone yourself.Best of luck with that though.
I cloned the code, you can find it here -

So that means the the forum has somehow blocked access for it entirely. Too bad, it was a very nice tool.
