Looking for live gig recording upgrade

[Kosko]

So my current set-up is:

Behringer c2s (sorry) > Behr Mixer > MiniDisc

What we get out of it is crap, but it is reference for us to look back at our gigs and examine what we did wrong/right.

I'm fairly new to recording so I was wondering if you guys could reccomend upgrades or styles of mic's I should be looking at for live-gig recording. Either bar room or outside enviroments is the areas it'd be in. Mostly bar rooms.

I also had an idea to make a mount at the top of the mics to hold my camera to record a video of the show as well.

The item that I'm forseeing as really needing the replacement are the c2s. I've heard the Studio Project C4s are pretty good and reasonably priced. But what else is out there? Is there a standard like SM58s are for the vocal world? What works?

Thanks to all for helping out another newb.
