Canon 5d3 Shutter Count

[Wildeye]

I'm looking to try and purchase a used Canon 5d3, what is a good shutter count to not be worried about purchasing? I'm looking at one that has 72.5k on the count for $1650. Is that a good count? I was told it can got to 150k for a factory rating. After it gets there does it have to be replaced?
I have been shooting a T2i and a SL1. I understand its now a full vs crop. Just wanting to step up my quality for nature photos and weddings. Thanks in advance.

The 150K number is an estimation by Canon, it may break before or after, there is no guarantee, however in most cases it will last more, as for the price, that really goes to your budget, on eBay you will find used ones with only 5K shutter accutation and in great condition, but the price will not be too far from new.

People always talk about shutter counts, but isn't the shutter quite cheap to replace?

Either way, the shutter can fail any day no matter what the count is. It can also be good for ridiculous amounts of use.
