Is there a calculator that estimated time to mining a block based on hash rate?

Most mining calculators make the assumption you will join a pool and give you results based on that.

A few weeks ago I saw someone has posted a link to a calculator where you could input your hash rate and get an estimate of time to solo mine a block.

Unfortunately I didn't save the link.

Anyone know a calculator that does this?
