Is a 2.5cfm vacuum pump strong enough?

Hi, I been planning to buy an AC vacuum pump. I see two deals at the store where I'm planning to make the purchase. Question now is, I see a 2.5cfm model and a 3.0cfm model. The price difference is about 40.00. I would prefer to save 40 bucks and get the 2.5cfm but I don't want to buy it if it's not even going to work. So I am checking with you guys.

I will be using it about 2 times a year only to recharge cars in the family, I would want it to reach -29 on the gauge. If the 2.5cfm model takes a bit longer to reach -29 than the 3.0cfm than I don't really mind, my main concern is I want it to be able to pull a vacuum to -29. If this is possible or anyone have tried this and would like to share their result please do. Any inputs is greatly appreciated. Thank you.

Whatever you buy, do not by cheap imported junk--you WILL regret it! Names like Mastercool, (available this site), Yellow Jacket, RobinAir, and other tried and true names will give you years of service. Although you say you will only use it only for family cars, you will, if you have purchased a quality vacuum pump, end up doing other cars, guaranteed, because it will be such a pleasure to be using a good unit. A 2.5 cfm unit is fine; that's what I use.
