Duct tests usually take about an hour depending on how many registers there are.
I've used the Minneapolis Duct Blaster many times. Always worked perfect for me.

Here are some manuals and quick starts. We carry both. There are discounts for HVAC-Talk members. They are both good products about the same price. It comes down to preference.
If you call Eric, our sales manager Monday we might have a few Retrotec Q32's left on the shelf on sale. They just introduced a new version called the DU200 which is a little lighter.
Here are some videos about the process also.
One thing I would also consider is a sent of vent caps or vent covers instead of grill mask as they are reusable and easier to install.
