If going over two channels your video camera can record,
I like the Tascam 2488. 4 phantom powered mics (8 max).
Records to an internal hard drive and then you can burn a CD
or send to Vegas via USB.

Mic selection depends on what you are recording.
Check sound pressure levels with a meter.

I'ld recommend getting the channel strip, especially for live recordings where the dynamics can be dramatic. It's always a good practice to use some mild compression on the way in to give yourself some breathing room if the vocal starts to get on the high side and having a knob you can quickly adjust at your finger tips like the mic pre adjustment can be a Godsend also. You can always just bypass the compressor stage if you don't need it, but most vocals have some type of compression on it. Just use it sparingly when going in. Usually, a 2:1 to a 4:1 compression ratio, and adjust the threshold so that you're occasionally seeing a -3dB to -6dB gain reduction on loud parts. Attack time is fast usually around 5-10mS and release is Slow around 250mS. I recommend leaving the EQ off when recording, unless it sounds really bad, otherwise do the EQ later in Vegas. Forget the gate stage on the way in, it's too risky of cutting parts off when recording, leave this til after the record if you need a gate function. You usually get a good mic pre-amp also with a channel strip so this is another advantage of using it. Another eccential feature I find in having a channel strip is having a De-esser feature, where you just want to get control of those right from the start.

Personally, I like the DBX channel strips, and I use the DBX 376, which has a tube mic pre, and also a lesser expensive model with a transistor pre the 286A.
