The good news is that thing was passed through reconciliation, and therefor can be repealed through the same process.
Changes to get the House on board with the Senate version were passed through reconciliation because Kennedy had died. But Obamacare passed the Senate with 60 votes and wasn't a reconciliation bill.
In the first post it clearly states that they can't repeal the entire bill with reconciliation.
Also:
Democrats will not assist Republicans in any repeal and later replace scheme, they will make the Republicans own it
