Digitcal Camcorder

[Evan]

I am thinking about buying either this or this camcorder because they're both a lot cheaper than I thougth digital camcorders were. I'm guessing there's a reason for this, are they horrible? I don't need anything that can take high quality video, and in fact I would prefer not to have that. This is mostly going to be used to capture stuff drunken insanity. So are they both sufficient for that?

My next question, and maybe the more important one, is how much SD memory do I need? The site has this info about the camcorders, "Movie file format: MPEG-4, Sound available / Movie resolution: 640x480 pixels, 15 fps; 320x240 pixels, 30 fps". Can you tell from that how many MB/minute I'll need?

I need to know by Saturday because if I buy it it will be to use on Sunday. I really appreciate any responses. Thanks.
