Best camera for low shutter lag at about 4MP?

[pasmommy]

On a budget. A quick cam is a priority in terms of having minimal shutter lag. We have two very small kids, and getting a good shot is difficult. Not to mention that with babies, sometimes capturing the moment is more important than the pic quality because those moments pass quickly (milestones and such.)

Here are our priorities, not necessarily in order:

low shutter lag
reasonable price
4mp
good quality pics

We would also like something fairly small, as we will be taking this camera to Disney World in the coming months.

Thanks for any help!

Let me add that we plan on spending more on a higher end camera in about 5 years when the kids are in school and our vacations are more scenic. We're anticipating technology catching up with us at the same time our finances do. :D So right now we're in the $200 range, lower if we can get it, but at 4MP I doubt that. Although I'd take a 3MP with a better shutter lag over a 4MP with a higher shutter lag, if that makes any sense.
