Thanks for all this info! From your second paragraph, it sounds as though I could buy 4 small, lightweight, digital recorders, each with its own wired, lapel-clip (lavalier) mic. Is that right? If so, that sounds like a great solution! (Either that or 4 digital recorders with WIRELESS lapel-clip mics.)

I don't know of digital recorders that come with lapel mics built in. You'd have to buy the recorder and mics separately. It's certainly one way of doing it, but bear in mind the caveats I mentioned.  
If you were to get four wireless mics, why not a four track recorder? Cheaper, and you don't have to press record four times each time you do a take.

Great advice. Thanks @stib! I'll just have to make sure the recorder can output each track as a separate digital audio file, so I can mix them separately.

<p>I'd like to buy 4 lavaliere mics for my video recording, and I need some education about lav setups.</p>

<p>I imagine that wireless mics would be easier to manage, but they probably cost more. I imagine I would need the wireless mics, and a receiver for each.  I'd also need a 4-track digital recorder. Or does each lav mic include a digital recorder? Finally, I'd need a way to transfer the audio files to my computer as either MP3 or WAV files. (Synching them with video should be simple; I'll use a clapperboard.)</p>

Most wireless lavalier microphones for video recording use are sold as single receiver + transmitter packages. I believe you can get receivers that take more than one input, but they are designed for AV production use (e.g. stage shows and so on) and are mains-powered and [expensive](http://en-us.sennheiser.com/wireless-microphone-receiver-module-system-em-1046). So if you want wireless you'll probably have to buy four transmitter + receiver sets. Wired microphones are certainly cheaper, but lapel mics and cables are problematic if your subjects want to move around. If they're not moving around, then maybe you don't need lapel mics.
