Recently bought 2 Game Spy D40's ($99.00 each) and have zero complaint!
No they don't come with infrared flash, and yes, they might take just a little too long between pictures, but the picture quality is that of my Olympus digital! Although the flash is only good out to maybe 40 feet, in broad daylight it oicks up movement 3 - 4 times that distance. I can set a camera up on a large open park and get good results in the day time.
Very pleased! Might get a couple more!
